Facebook made my life better, but that does not matter to you, because my life without Facebook would revert back to bad which you are completely cool with. That is the core of your argument.
> But what the FB does is creating a false sense of friendship,
That is something you made up. You
>, instead of focusing to a few people you really like,
I am focusing on poeple I really like and Facebook made it easier for me to do so.
> go for a beer with them, actually bond or find another friend,
That assumes many free evenings and physical proximity with similar people. That assumes that going regularly for beer as an easily available option that does not costs other things that are important - work time, children time and other duties time.
> At the end you finish with not having a single real friend in your live, but you rather spend a lot of time on chatting with irelevant people.
That is life. That is also infinitely better then being alone. Having close friends physically present around me with a lot of time on both sides might be even better, but that is not here not there. You ignore the actual choice "shallow or nothing at all" and talk about made up choice "shallow or best friend".
I guess that you have zero idea what it is like to be socially isolated. That is happy for you, but people unlike you exist. Your response to them is just a bunch of condescension.
> FB gives you a false feeling that your social life is ok, while here you know that you only chat with strangers.
Again, you made that up. You dont know what feeling I or other people have, so you project cluelessness into them. People are not off the grid because of Facebook, people were off the grid all the time. Both those with and without Facebook, due to how life is lived.
That is why it became successful in the first place, too many people found what it provides helpful.
I did not downvoted you, but I guess it happened because you built your argument of projecting worst possible motivation on people who are not like you.
