A service robot is a robot that performs useful tasks for humans or equipment. It is used for commercial task, usually operated by a properly trained operator. Examples are cleaning robot for public places, delivery robots in offices or hospitals, fire fighting robot and surgery robot in hospitals.(https://www.eu-nited.net/eunited+aisbl/robotics/robotics-market-introduction/index.html)
  Robots are also used for tasks considered to be too dangerous for humans. With this brief introduction of robot, we shall be considering some impacts of robots on world economy.
Robots Increase Productivity and Competitiveness: When used effectively, they enable companies to become or remain competitive. This is particularly important for small-to-medium sized (SME) businesses that are the backbone of both developed and developing country economies.
 It also enables large companies to increase their competitiveness through faster product development and delivery.https://ifr.org/img/office/IFR_The_Impact_of_Robots_on_Employment.pdf
Job Creation: Many people fail to realize that robots are creating new, high paying jobs that require skilled workers. While it is true that robots are replacing low skilled workers and automating the tasks that they perform. Robots complement and augment labour, the future will be robots and humans working together

Would robots be cost effective if they did not kill many more jobs than they create?

Society can adapt to massive job loss. Culture can shift to become less reliant upon governments and the private sector for bread. Self sufficient farming and off grid living would become norms. The better suited people are to producing necessities like food and energy. The less they need jobs and working hours.

Of course the real issue is productivity advancing significantly thanks to technology and automation. While the tangible rewards are not equally or fairly distributed.

Robotics does the work that's been assigned within the programmed time period as per the design or the work allocated. This way the human work force usage is being much decreased. Robotics play a big role in the mass production as well as in the increased manufacturing to the fast moving World. By the time robotics affect the human living through job cuts, and to the development happening with time through automation governments should take necessary steps to keep the common people have the life.

I have seen many people argue that robots take over human jobs in some articles I have read and I so think as that. How do you talk about robots creating jobs? Robots are the major reason that there are job loss because they are multi tasked and can do many people's jobs in minutes. For example in a shoe making shop or cobler, some jobs are easily and neatly done by machines. This is same for other bigger organizations and banks. In a bank, the cashier might not need an assistant because the counter machine is there. I think robots is faster, it has its advantages and disadvantages and human loss of jobs is one disadvantages.

Robot are programmed and no matter how sophisticated they become can not replace human work force where human feelings/instincts are to be/ are needed, like in medicine robots can bring medicines/materials to patients but can't connect with the patient they way a nurse would.
Robots can be added help to human work force, more of a faster hand in labour in factories, delivery aids, run errands/message, no doubt it has a positive touch/influence on the economy

The human power that is still needed in powerful work and robots only helps to carry on the work neatly and the rest of the humans will make it better for jobs, I think robots cannot change the economy in other ways but only help lighter human jobs.
But this is also a lot of development about robots on the influence that will be needed, as you mentioned, and it is only an introduction, not operation, nothing more but with robots we can work faster in any field, including in hospitals which are widely used with technology robot.

Robots have been with us for a while now and have been implemented in sectors like military, medical and manufacturing;
• Drones are being used for reconnaissance and to attack enemy territory without needing to man the craft.
• Medical field has relied on technological advancement to improve the quality of health care.
• The manufacturing industry has also benefited, with production in the U.S increasing by more than 40% in the last two decades;

This increased production has of course had an effect on employment which is 29 percent lower than it was 20 years ago (https://www.nytimes.com/2016/05/08/upshot/the-economy-is-rigged-and-other-presidential-campaign-myths.html), before the pandemic situation of course.

Job loss is an inevitable factor of development, computers which evolved into mobile phones made a lot of jobs irrelevant, same with engine-powered vehicles which has been utilized in transport, agriculture etc. Through this developments people have evolved and I believe we would do so in a robot driven world. We wouldn't stick to using hoes for cultivating lands, because it created more jobs than tractors.

It also creates low skilled jobs. Mobile phones like apple employs thousands of low skilled laborers (they could be paid better than they currently are, but that's a discussion for another thread). A lot goes into the making of a robot, raw materials development as well as manufacturing, and on a global scale it would create lots of jobs in various sectors.

Man you got to delete this shit before a moderator catch you, I'm not tolerating any action like this in the forum but taking your rank consideration that you're still a newbie, I guess it's not too late to change your type of routines here in the forum. Your account might be banned, and your 10 merits will be wasted. I'm wondering why others still commented on this one  ???

The impact is the future, and what we could do with it. Right now it is quite important to realize that many things we build are still handmade, obviously we use machines for everything to build them but there are people working in factories, there are very few rare places that requires no person at all, tesla for example has only supervisors who check the robots and see if everything goes according to plan but they do not work on the car themselves.

This will get bigger, eventually we will reach to a level where people would actually be capable of not working on manufacturing jobs and machines will be capable of building everything with maybe few human supervisors and that's it. At that point what will humans do? What if eventually every job can be done with a robot? or a machine? How will we earn money?

This is a pretty interesting topic which is really not much talked about. Being working in a corporate I have seen how robotics is slowly coming in and making some significant changes in labour costs and efficiency. Moreover combined with the new trend of IOT and ML this field is actually growing at a much gradual pace. Actually not only for SME but the big brands are now trying to deviate themselves from traditional industry to robotics Industry. I had a visit to a soft-drink manufacturing company of Coca cola. They have opened a new plant. The new plant is around 5 times more productive than the previous plant(which they made just 4 years ago).Moreover, this productivity has been reached by around 50% redued workforce. There are just foremen left who merely keep a track that everything is fine.

Rest the whole process is completely automated from start till the end. Moreover every bottle is tracked individually in the computer screens regarding content as per their schema. They said that the customer who drinks the bottle is actually the first person to touch the bottle or maybe the shopkeeper who gave him that bottle. This actuallly is a pretty cool thing but at the same time if we see for small scale workers it's pretty disheartening too.

Can't disagree with you. Change is inevitable and I think maybe it's on government that they need to reskill the future labour in such a way that there services are needed in these futuristic areas. The traditional manufacturing setup isn't really going to last for long.

Well, with jobs that needs precision and speed, usually factories are using robots or an AI rather than a human. That being said it doesn't make the human's work lighter, it will be the replacement of human's job in this case. It is true though that right now there are these robots that makes our lives better, faster, efficient and convinient but that would also means less employment in the future.

In the developed world the use of robots has increased manifold in various sectors including industry and robotics can play an important role in increasing the productivity of the industrial sector and in the great prosperity of the country which is slowly becoming an industrial dependent economy. Also since humans have to work within a certain time frame and the pace of their work is not always the same due to physical fatigue or exhaustion the robot can be a human collaborator. And the current world will reach the peak of further development.

I figure it will affect awful on our economy.

---

Individuals will become jobless if each organization starts employing the robot they don't have to pay compensations to robots so they'll replace humans with robots.
The second terrible thing is peoples will become sluggish by giving their work to robots.

This is a burning issue and will be one that we will have to soon grapple with besides disruptive climate change. Like everything else with Capitalism, you inflict damage first and then try to bandage the situation. Robots and automation lead to better profit margins and every single industrialist will prefer it. When it comes to the likes of amazon, Uber which are primarily into "Services" business, they are also looking for ways to reduce dependency on low-skilled human jobs like delivery personnel or warehouse workers.

People give the excuse that the jobs will move to better paid, skilled jobs. Yet, who says that every single human being is suited for these kind of jobs. Is a future foreseeable where low skill jobs are not needed because there are no low-skill people? What if we end up with billions of low-skill people (as is the case today) but no jobs for them? I love this vision of self-sufficient living. It reminds me of Luke skywalker living with his Uncle and aunt at Tatooine fixing old robots all day while his uncle works on the farms.

This could indeed be a reality but fundamental societal changes like these and legislation required for this hardly ever keeps pace with the breakneck speed of capitalism, or should we say, crony capitalism.

Robots will be efficient if they are not built like a Gundam Mech, that thing will collapse under Square Cube Law. The impact of Robotics in economy is evident, they can be utilized for Deep Sea Exploration, exploring deadly environment like Chernobyl Power Plant Core and the most famous is Space Exploration. The funding for the aforementioned missions would be more expensive if they did not use robots, definitely the job generation would be the most affected if robotics are adopted in industries and commerce. This conundrum will be difficult for governments to solve because we live in a capitalist society where everything comes at a price.

Robots or machines will definitely replace most employers in the future because they are faster and more productive, and business owners don't need to pay these robots' salaries. That is why jobless people will increase their numbers in the future. It is the reason why only computer programmers and developers will exclusively remain if that happens because they are the ones who create and program robots to function.

Naturally, even with Robots, the thirst for knowledge and improvement inherent to humans wouldn't be extinguished no matter what. We may be just staying right now at robotic development, but within a few centuries, or maybe just a few decades, a lot of possible things could happen. Interstellar travel could be one.


Isn't that temporary? Currently, the production of robots is more for specialized actions and activities such as what you said, but in the near future manufacturers would employ robots themselves to create and process more materials to create more robots that they can sell/use for other purposes. Robots are indeed opening up new jobs but that would probably be temporary, and more likely that job losses would be more prominent than the amount of jobs robots could provide. Ofc, this isn't necessarily a bad thing, with how the world is proceeding towards an automated world, having humans enjoy life while robots do work is a vision that most would have probably imagined before.

I guess this depends on the job, right?

Most of those people in the producing industry would definitely make or find an AI to cut their budgets and make their manufacturing faster, cheaper and efficient. As you said, that would just mean that people in these places would just be in maintenance or maybe engineers that would monitor these. I guess this will also depend on the country.

Work that is repetition and memorization has begun to be eroded and replaced by the development of automation technology, robots and artificial intelligence. Technology (industry 4.0) can disrupt or destroy jobs that have been done by humans. Manual labor and repetitive jobs are easily replaced by robots and are affected by automation.

However, there are some human skills that machines cannot easily replace, such as empathy, creativity, and analytical skills for complex problems. The development of students' IQ (intelligence quotient) without honing their EI (emotional intelligence) skills is no longer relevant today and in the future. It is necessary to develop people who are not only memorizing, doing manual work, but who are able to do analytical work, creativity, a complex problem solving. It can only be done by humans through the interaction of the brain and heart. Robot can replace the intelligence of our brain, but he cannot create feelings.

It's a normal progress process. In the futre more and more jobs will be replaced by robots

I guess by Robot you mean atonomous machines (not necessarily the human/animal shaped robots)?

Well, I will probably only buy simple autonomous machines or complex ones that I fully understand, Or build it myself(or buy the custom-made).. . Will prefer those I can always easily control.    If I will ever use robots or autonomous machines, I will use those that cannot be connected to centralized internet. And I will set their rules for decentralized  control on a good or well decentralized network/internet .

Honestly considering all the regular stuff we need to survive, I do not think that it is impossible to make them all automated. What do you need most in your life? Groceries right? Like water, bread, flour, whatever? Or maybe you want to order fast food? A burger and a shake maybe? How could these not be mechanized?

Of course we still need a human to be there to check the situation and see if everything is going right, but we could totally get all of this done. How? First of all you create the warehouse as a place that is machined, it won't be like a regular grocery store, and when you send order from mobile app at home, the warehouse machines will start working, get one cart which can be automized fairly easily, go to each item which will drop to the cart and when it is over it will load up to a car which we know can be humanless driving with new cars, comes to your home door, you pick from there. Zero human worked on it.

The impact of having robots replacing human tasks, which I realized, was that more people lost their jobs. If we compare it to before the existence of robots, at least in one industrial area there were so many employees that the existence of robots made many human positions replaced. I am not sure that the robot will advance the economy more equitably, because it will only be enjoyed by the upper class and vice versa, the lower class society with many shortcomings will still find it difficult for them to get a more decent income and job.

I do believe that we all understand how Robots take over the jobs of the people , it is advantageous for the employee of course since it's more like a one time investment.

But then again there are hazardous working conditions no doubt , which actually is good when undertaken by the robots.

But more or so they will cause positive economic growth altogether but at the same time the individual economic growth will be halted for sure.

The big companies will continue to make profits and the small workers will be overshadowed by the profits made by the big businessmen

There are so many advantages to the increasing number of robotics, same as there are disadvantages.
The most that a lot of people are complaining about, is the part that humans are going to be losing their jobs because of these robots. This doesn’t affect those who are Business owners, it’s only the employees that are being affected.

Business owners always have plans to keep maximizing their profits, and they are always ready to do whatever it takes to increase their profit, and they can choose to use robots to replace humans in areas where it’s possible for them to do so.

These two examples aren't the best because drones aren't on full autopilot. It's true that they don't require a pilot but are flown remotely from base so the pilot is there on the job. Drones also require almost as much maintenance as normal planes.

Medical robots also work under surveillance. The same job used to be done by a surgeon but now you need a surgeon, a robot designer, a robot manufacturer and someone to maintain and fix any errors and issues between surgeries so you need even more jobs for what used to be done by a single man.

Robots are essentially slaves, of illegal migrants if you prefer, that work in dangerous environments, like factories or mines, or doing tedious works. On addition to that they are working without health insurance, or requesting paid leaves). This drives  prices of goods down,
And  salary for the middle class down.
So this means robotics had a real impact in our economies, and primarily on weaker portions of population .
One solution would be to tax robots, like it was  proposed in the Eu a few months ago.

tax the owners of these robotics companies. because these robots dont know anything bout it. but are they already doing that?  we just don't know to what extent?
 but lets admit it, robotics will save a lot of human efforts and at the same time get good performance/results.
we are in the age that we need this industry to save our resources and put them into good use.

The use of robotics in the business world can benefit business owners, because it can reduce employees and this can reduce
the burden on the company to pay employee salaries. But on the other hand it can increase unemployment, even though robotics
can do jobs that humans do, but not all sectors can be done by robotics. So in fact, the existence of robotics forces humans to be
more creative and work hard, so that they are not replaced by robotics. In other words, robotics forces improve the quality of human
resources, of course this has a good impact on the economy.

There will be an adjustment to education too if that happens.

Since manufacturers might be focussing more on getting AIs or robots in the future, education will be shifted into something that would adapt to these changes. Maybe they would let people handle things that couldn't be handled by robots like medical cares and stuff that needs the warmth, the intelligence and knowledge of a human being.

Are you sure about that? I have already seen robots painting, writing poems or books, as well as being used in medical care as nurses, taking basic task like delivering pills, but with “emphatic interfaces”. Development is exponential, we can only hope humans can keep par of this.

^
I'll add that just the single use of automated cars (robot drivers) will revolutionize transportation. Think of how many people around the world work as taxi drivers. It may take another 50 or 100 years but sooner or later they'll all be gone along with all truckers and train machinists. What will those people do?
You can see them having problems already with widely available eletric vehicles. Why would you get a cab and have to ask the driver if he'll wait for you at every stop when you can get a cheap EV car for an hour, go shopping, pick up kids from school and leave it parked anywhere you want when you're done?

Impacts of robotics on the world economy can be seen to have both advantages and disadvantages in a long run. Automation do really makes more productivity compared to manual work for it takes lesser time and a lot more accuracy and efficiency working with robots compared to human manual works that encounters human related errors due to factors related to experience, age and other stuff that affects their working capacity to job unlike with robots that are programmed to do specific tasks that are most likely a lot more impressive considering the time and the product of work they produce, which is all in all a favorable advantage for the existence of robotics into the world economy for it creates seamlessly fast productions which is good for the economy. While on the other hand which is the disadvantage that humans are being replaced for the works are already can be done by robots with a lot more efficiency and productivity which can be a reason out why there could be a possibility of an increase rate on unemployed individuals because of this.

Oh, automatic/robotic drive will completely change a lot of industries. Think about mechanics (no more car accidents), insurances (no more car accidents), parking lots not needed anymore, traffic lights neither, and even how we build cities will be totally revolutionised. Cities changed when we shifted from horse powered transportation to ICE transportation, so I guess the next big revolution will be automated drive.

Automation in all fields, especially the industrial sector, is considered a certainty, but many people are not aware of this problem, many individuals do not make preparations to compete with robots. Indeed, the robot vs human period will still occur in a few decades, but the government has not really carried out socialization and even made educational programs so that human competence can be above robots.

The way governments currently organize education may no longer be appropriate for a world facing rapid technological changes. The government is not updating education, training and political institutions to deal with it, and making transition plans so that talent can fill looming skills gaps.

Mechanics will still be needed for regular maintenance, if not for the paint job after a crash. Considering that most of these cars will be Electric, automated and have fancy software installed, there will be a whole force of software + hydraulics + electronic technicians and Engineers in place of the mechanics. I suppose they'll be better paid. Car insurance will probably cease but theft/ sabotage/ natural actions like a falling tree would still need to be considered.
No more drivers but who can say that people wouldn't still want the luxury of a chauffeur driven car. Maybe all the people who cannot afford an "automatic" will go for the now much-cheaper drivers.

Robotics and automation in general will surely disrupt a lot of jobs but with proper planning and regulation, they can also result in newer job patterns.

The impact of robotics on the world economy in the company will reduce the number of employees because the robotics will do every task and the robot will do all of the jobs. Maybe we will see robotics in many places, help human works, and be available in the store, public area, and office. We will see much unemployment because they don't have enough skills to compete with the robot. Everything will be automated, and I think we already in that phase now.

I guess so far in the history of the world we have seen the rich people do whatever they can to stay rich and not help the poor, they have always been like that, it was true 2000+ years ago when people had slaves, it is true today when people have "modern" slaves where they pay a wage that is barely enough to survive and usually in debt some way to keep working and never do what they really want.

So, if the robotics manage to take over business a lot and rich people could use robots instead of people that means they will pay once and not pay salary, so others will have to starve to death. Rich people will not suddenly go "well we use robots, so maybe we should all pay high taxes in order to pay UBI to unemployed people" that is never going to happen.

Robotics had get into economy with a intention of reducing employees more easily and to reduce their payments.For the company, it maybe a profitable one.But to the workers and to economy it was not a good one. For workers,they lose their monthly salary and it will impact on the real economy.

actually not only that,Robotics are being applied to some company for faster and more accurate working because robotics is much efficient than Human IMO.
so having robots in business makes it profiting more.
though there are jobs that can't be applied by using robotics and that will remain the bread and butter of the human being.
But for me?i had try to use Robot vacuum and i hate it,i rather do the Job manually than having a robot for that specific task since my House is full of things that valuable for me and my ancestors .
i regret buying one.

And that sucks the whole world because the employee will lose job and the physical works will sooner be gone.
what will happen to the family of these people?this is not fair for the humanity.
no wonder that sooner we will see all robotics been attacked or break by the people to stop dismantling their jobs.
we will be in great loss if this continue because yeah businesses will grow and economy will increase but what about the people?

To be honest, our future when it comes to technology is pretty scary for humans. Robots might replace humans when it comes to accurate work, never get tired, and could work simultaneously but you'll have a boring working environment. Working with humans are more lively and motivating than working with robots, because we help each other to bloom and comfort each other when down. Now, with the robots, it would feel like we're gonna lose humanity, just like what we see in the sci-fi movies.

AI might evolve to something chaotic like they would have the ability to decide on their own without human giving them commands. When that happens, we just created our own monster that we cannot control.

It is certainly dependent on how people will perceive the impacts of robotics within the world economy if it would be good or bad. But certainly if you will look at it most specially making big countries as a basis for having advance technologies (having machines, robots) to do specific tasks, you will already can come into conclusion that presence of robotics in the world economy certainly do have a good impact for it creates more productivity compared to working on with pure man force because as the technology advances, the more we foresee the possibility of creating robots and machines to mimic or do what people can do considering to cancel out potential human errors to create faster and a lot more productive and explicit rate of job being well done in a short period of time. The only thing negative that I can see to be the impact of robotics is that replacement of people will be present because robots does not need to be paid off after purchasing, creates more products, low maintenance, compared to humans that are the opposite of the ones stated. There should be still a balance in nature between humans and robots to be able not to make happen that there could be a possible future that robots will be dominant over people.

There are pluses and minuses associated with using robots to replace human labour. On the one hand, this automation can encourage high economic growth because robots are considered to provide efficiency for industrial productivity. On the other hand, this condition holds the risk of hampering labour absorption, considering that many human jobs can be replaced by machines or robots. Obstruction of labour absorption will harm a country's economy. Given that the economic growth of a country is strongly influenced by the level of public consumption. If it is difficult to get a job, of course, people's income as a source of spending is also hampered and in the end, it hinders national economic growth.

With that scenario, poverty rate will definitely increase as the jobs available for humans decreases. We might experience famine from small place that will eventually become globally.

I have a scenario in my mind on what might happen. People fighting for foods, rebellion will be a normal occurrence in different states and countries, struggle for power, and the gap between rich and poor will get extremely far. Sure, there is advantages such as rapid increase in economy, innovation to technology, Precision and accuracy in products, and low maintenance vs wages for employees. But where is humanity in that?, where is the stand for us people?, and where is the fairness that should be given to as with the promises from the governments?

I think the workers need to improve their skills to be still used as the company's employees. But when the robotics is used, we, as humans, may search for other jobs that still use humans as the workers. I think robotics will not give much in a few years later because the robotics itself still in development. So we as workers can feel calm for a moment while we can learn more to find better jobs.

Robots are helping humans with some tough jobs. They help increase labor productivity many times and replace people in some production stages.
The benefits of robots are enormous for the economy.
Robots or machines also help people in housework.
I think that Robots are beneficial and harmful to life as well as the economy.
It helps people to solve some workgroups and is highly productive but also makes us erase skills in those workgroups.
For example, We use washing machines and robots cleaning the floor often, we will not know how to wash clothes by hand or clean the house.
Car assembly robots save us effort but also eliminate our skills in assembling cars.

Well I wouldn't say that we have robots, I like to call them machines, but we can argue which term is better and more accurate. Machines are machines, they can work 24/7 with the same peace, and single machine can replace many workers. In long run it's cheaper and more productive to have one big machine than 100 workers for example! What is the direct impact on economy here? Clearly higher productions means higher supply, and that will eventually lead to over saturated market. That happens even now, we have too much off everything, but not enough people to buy everything that has been made! Bad system, I am saying that for years, we are spending recourses for things we don't fully use, it's a real waste of the nature around!

Although it may improve such things, SMEs don't really need such huge productivity when customers are only limited, unlike big/factory businesses. Also, the cost of having robots is too expensive for most business owners to fund it when their income will probably not enough.

If this is about the positive impact of robotics, of course, it does have a positive impact knowing that we are adopting technological innovation since we are seeing how technology is making things easier. However, for now, it's still quite early or most people are still not ready for this big adoption because this kind of innovation will cost a lot.

Today, truly robotic machines greatly facilitate human labor and reduce the time and difficulty of production in many factories and enterprises. The quality of the products and the efficiency of the production process have grown many times over and this, of course, greatly affects the economy by developing its potential. But if we talk about those robots that people are most likely talking about, which we see very often in science fiction films, then it will take a very long time until they appear, since today there is no point in massively creating and producing a machine that will visually remind a person, moreover, this is not a waste of a lot of money.

Now that we are into the continuously rising and improving modern technology that from the traditional now gets to digital and modern advancement making the rise of machineries and robots, we have seen how good is the impact that this have employed into our global economy for works are already been easily and fastly done in short period of time because of automation due to programs being set to follow by the robots producing more higher quality of products and services compared to what human can do. It just so happen that with the continuous innovation of robots because inventors do want to achieve a humsn like behavior to robots, humans can possibly lose their jobs in a long run for robots will take over and do all the tasks.

The "robotics" is a questionable one in this example but what about self driving cars? Do you consider that as robotics? If we do that, we are talking about drivers not being a job anymore and there are tons of people who drive for money. Uber famously paid upfront money in billions to Tesla for self driving cars and if they could get it a bit more licensed and agreed by the government as well we are talking about self driving uber cars.

You call one, it comes to you itself, stays there, you confirm you are in it, and put in where you want to go, it takes you there, stops, you confirm you are out and you pay up and basically never even see another human in all of this. Same goes for trucks as well, I know self driving trucks are a bit further away but it is worked on so that means goods will be transported with trucks without any human driving them in the future.

in the future, our competitors to get jobs are not only humans <-> humans but also humans <-> robots..  high-risk jobs will of course be taken over by robots in the future.  In this modern era, we as humans are required to think hard about how to use the resources and opportunities that are created.  Robot and AI have been confirmed will take over several jobs in the future but new jobs will appear along with technological developments..

When it is still in the period of adjustment, of course, our economy will be disrupted because the explosion of unemployment cannot be denied.  the good news, it will happen in the next few decades so we can anticipate it from now on..

I would not say self driving cars are run by robots, it's just a software doing it. For me a Robot is a physical thing which helps humans in automating production tasks. Maybe it's because I watched too many Terminator movies, but Robots have usually atleast some parts which look human, like an Arm or so. Robots and Machines took over so many areas already in the last 20 years. For example, production and essembly lines became so automated and less dependend on humans. In my opinion this trend is likely to continue at a faster path. Humans will not be needed anymore in production and construction in 30 years from now.

My cleaning robot clearly disagrees.
As you correctly stated robots are tools in human production. They don’t need to have a human appearance, or rather have an appearance at all: a driving robot is (almost) entirely software. A self driving car looks almost exactly like a human-driven car.
Human like robots might be needed only in very limited industries (sex, for example).

Yes, the exact robots aren't the machines that are designed to run based on the software programmed to perform tasks. As stated human like robots are very specific on few industries like sex. On this pandemic the need for such robots have increased a lot. This is being revealed based on the source from a private company's survey. During the pandemic the sex robots industry has experienced good boom in growth while majority of the industry were facing the hard time. From an article saw a data where 22% of Americans interested to have sex with robots :o

Source - Human Robots for Sex (https://bigthink.com/technology-innovation/robot-sex-doll-study-yougov.amp.html)

Because machines are just better workers.

They don't need to eat and sleep and can work all day. They don't get bored or tired. They will always excel in jobs that require repetitive motion.

I'm happy they're taking over jobs people had to do in bad conditions like packing frozen food.
