All you are saying is true, people try to impress people forgetting that being themselves is actually the best way to navigate a sensitive place like this forum. The moment someone is pretending to be what they are not, it will not take long for people to get the clear picture and that will only breed more problems for such person. I think that is even the main reason some people resort to using AI and thereby put their account at the risk of being banned. Being original and confident is always the best approach and will enable the user to grow naturally.
I don't blame them, the system wants them to be that way. You see there is a rule and regulations on the forum and there are consequences to them if you break them, so they try to act in accordance to rule, even the people that does not understand the basic part of Bitcoin pretend to know about it which is why from their post you will know that they are trying to know something but they don't know it because they are forcing it the knowledge in their write up.
What every newbies is expected to do is to make sure that you learn first, understand the little you can even if it's not the complex part, it will make the forum easy for you and it will be fun to flow together with rest of the people in the forum. A place where you can have fun and do things that you want with others or a place where you want to have fun with other people but you don't understand the language but you have to pretend, choose 1 for yourself.
