If I understand what you are saying, you are saying we already have ASI since our AIs can do things humans can not do?

Well, there are still things humans can do which our AIs cant - once that is no longer true there is an argument we will go directly to ASI and skip AGI.

anti social in terms of not doing what is considered socially acceptable (shouting at you for no reason, not helping, blocking a way while standing there, damagin something and walking away, etc)

Abbreviated from "asocial". It's mostly an insult for egoistic assholes, people with lacking manners, dishonest people and stuff like that, but also for poor people. Don't expect too much accuracy.

It obviously depends on the character, but a monk really should get their dexterity to 20 instead of taking mobile at level 4.

Because attacks already had a chance to miss you due to existing AC, and you already had an attack roll bonus, you’re adding a lot more than an extra 5% chance to hit (if your chance to hit was 50%, you basically boost damageby 10% by going to 55%) and to your chance to dodge attacks.

And for a monk at a table with optimized characters, you absolutely have to get that dex up since there are no feats like GWM/SS that boost your damage all that much and you absolutely need to do better damage. If you take the mobility feat, congratulations! You are now fast enough to do bad damage everywhere.

But for something like a fighter, they can get way more out of polearm master and/or GWM than any boost to strength would usually give them, so in that case it’s a clear boost.
