As @nc50lc said the GUI apparently has the option which makes it easy but remember that "easy" for most users mean a very friendly button in the GUI that they can click to perform an action not a console they have to type commands in. Specially when you also consider those who may not even know what bech32 is to know they have to attach an m at the end too.

As far as the protocol is concerned, it does not care where the coins come from and where they go to. In other words you can send from any script type to any script type.
The only problem that might be what you had in mind is when for example you want to withdraw from an exchange to your Taproot address and that centralized service doesn't recognize this type of addresses.

There are network monitoring and capturing tools that can capture all your network activity. For example Wireshark. You can set it to only capture HTTP traffic over 8333 port (42630 is your local port not the peer's) and filter the result based on bitcoin messages. Then look for a version message.
This way you can clearly see what the problem with that message was, for example if it was shorter as I said in my first comment or broken.

Here is an example from Wireshark after connecting to a random TestNet node. The part on top shows the deserialized message while the part at the bottom shows the raw bytes:

You are right, they are still printing physical money (cash) and I should have been more clear. But the biggest part of the money they "print" is actually digital which was my point. For example during the early days of COVID pandemic FED printed trillions of dollars. There is simply no way to physically print that much cash.
There is also not even serial number on the notes to cover all that money. I believe it is less than 11 digits for US dollars which would be 99,999,999,999 or 99 billion assuming the fixed letters are digits too!

You should have captured the data stream itself instead of the modified result that core reports in order to know what that other client is sending you. But this behavior (no service flag, no block height, no relay; and if you request headers they won't reply) is usually common among scripts such as crawlers and spy nodes (basically custom written code) not actual full nodes.

Majority of wallets already support SegWit version 0 addresses. You can use bitcoin core if you are fine with running a full node or choose Electrum if you are fine with running an SPV client.
However I have not yet seen any wallet that lets you create SegWit version 1 addresses (aka Taproot) easily.

They are both SegWit transactions but what you call "SegWit" is the version 0 and what you call Taproot is version 1.

Version 0 was introduced in 2017 and it was the first attempt to increase the block capacity among other things and pave the way for future development.

Generally speaking when you use SegWit transactions your tx weight becomes smaller so you pay a smaller fee.

Version 1 was introduced recently, it introduced Schnorr signatures which can take up smaller space and Taproot changed the way scripts work and opened the door for some interesting smart contracts.
For example your script could have many branches but you only spend the output by revealing one small part of the branch. Or when it comes to multisignature scripts you could take advantage of Schnorr signatures and combine all the participant keys and only publish one pubkey+signature unlike the previous versions when you had to publish all pubkeys and signatures, this way the tx size is significantly decreased.

Use SegWit version 0 since there is no user friendly way of using version 1 (aka Taproot).

Not necessarily. For example bitcoin core supports both versions but doesn't have any LN code while Electrum supports version 0 and also LN.

Technically innovators aren't affected by the price and the market drama that much, if anything I'd say during bull markets when everyone is happy is a better time for "building" since it also attracts more people compared to the time when the price goes down and the internet is filled with gloomy discussions that bums everyone out.

P.S. The picture shows this too with the dude wearing a white hat on rightmost part of the picture who is present in all the stages with the same happy face!

Each node has its own mempool and its own rules for transactions that they accept in it. Majority of nodes use the default settings that rejects 0 fee transactions and non-standard transactions meaning such txs with 0 fee would never be propagated throughout the network just like how OP's transaction never reached 99% of the network and was only found on one explorer with loose rules.

To be clear the address you posted was not created from a public key because it would be impossible to find such a big HASH160 collision that corresponds to "759d6677091e973b9e9d99f19c68fbf43e3f05f9". What they did to create this address was to simply create the Base58 string then brute force the last couple of characters to have the correct checksum.

You don't even have include the version string and some other fields in your version message and due to backward compatibility bitcoin core ignores it all. Basically after the processor reads your network address information the message stream could just stop there and it would be fine (meaning it can skip: nonce, subver (version string), height and relay bool).

Bitcoin is a good solution because it is decentralized and has a cap which makes it deflationary. That means CBDCs and anything else that is centralized which includes majority of altcoins are going to have the same fate as fiat not to mention that CBDCs are the same exact thing as fiat.
As the centralized economy collapses, it takes everything centralized down with it.

From the first day humanity started using fiat the inflation has been caused by printing more money than you should and US has been printing trillions and trillions of USD without it being backed by anything but a false faith. The inflation you see today is because of the fact that 60% of the world economy is slowly dumping US dollar as reserve currency and all those trillions are coming back to America causing high inflation.

This is not the first time US dollar gets dumped hard either. Last time was when Europe found out USD is not backed by gold as promised so they dumped it and over about 6 months the value of US dollar was halved.

But it is always easier to blame it on a conflict on the other side of the world or on a senility of the old man in oval office than to solve the actual problem.

You can not make the price stable, it becomes more stable naturally in time. It all comes down to adoption, to put simply as the market grows manipulation of it becomes so much harder. You can already see it becoming more stable if you look at the bigger picture for example comparing bitcoin market of 2010-2011 with 2021.

Bitcoin can have a stable value some day but its price will never be stable because fiat will continue dumping so bitcoin price should always rise.

I'm afraid the consequences of this assassination could be far more dire than what we see, from political turmoil to international conflict namely between Japan and China that historically have had a lot of problems. They say the Japanese legislature now is not going to dare oppose Abe's reforms to the pacifist constitution and their dependent and severely limited military.

All of this could end up messing up the economy which in turn could cause more volatility in bitcoin market.

Nobody actually "prints" money these days, everything is digital. They just type in a  bunch of stuff in the computer and they invent trillions out of thin air. That is how the fiat system works. There isn't enough paper in the world to print all the money in it!

Keep in mind that you can not compare the two together. Cost of printing fiat does not determine its value, in fact the definition of a bank note is that its value is so much higher than the cost.
But when it comes to bitcoin, although the cost of mining a new coin doesn't determine bitcoin value but it is directly related to it. Meaning if price is $1 the cost of mining is close to $1 and if it is $10 million the cost of mining is close to $10 million.

AES itself is standardized, you just have to know what you are doing when setting the parameters such as padding. cipher mode, etc. so that you can replicate it using any other tool.
BIP38 itself is not that popular either. The major wallets don't support it and the implementations are rare and mostly web tools that may be open source like bitaddress.org.

In other words European Union is going to condemn Russia only in words but in practice they will continue supporting the invasion because their "economy" is too fragile that it would go under if they do otherwise... #hypocrisy

I liked this view. At the end of the day if we are seeing that the adoption is increasing in the long run and regardless of the short term drama, that means bitcoin is successful since it is doing its job. This adoption increase is mostly reflected in the long term price rise (2 years ago it was $3k and now it is $20k).

The type of adoption is not important either because bitcoin provides many utilities for different people. For example it acts as a hedge against inflation or as a censorship resistant currency or simply for speculation or as an immutable timestamped database and a lot more.

There is a lot of posts about the price because the market has been very volatile these days after the big crash that surprised everyone. On top of that you are looking at topics in places that are focused on the price like the speculation board but if you go somewhere else that is not about the price like the technical boards or sites like stackexchange you won't see any discussions there. Not to mention that the speculators are more vocal than others.

In any case, bitcoin price is important because as a currency it has to have a value and that value is reflected in the price. It also has to be more stable (which it still isn't) to function better as a currency.
Price also affects bitcoin's security since it directly affects the mining profitability and the hashrate.

By anything I meant literary anything not just another signature. For example it could be replaced by an arbitrary message like <foobar> OP_CODESEPARATOR

If it can be discarded that means it is pointless and is not solving anything.
You see, the locking script should be designed in a way that it mandates all the unlocking script parts. For example in a P2PKH locking script, it requires 2 items: a signature and a public key and neither one can change meaning you can't use someone else's public key or use a different script to spend that output.
