technology is just a red herring. GTA-level whacky NPCs will have NPC behaviour regardless of what situation you throw them in.

The same "person" that shows absurd behaviour like that, assuming it's not just rage/clickbait, has absurd behaviour in a completely technology disconnected world as well.

The only thing that might differ is that it's not as outwardly obvious. Those behaviours are a result of who they are at a person (whether this be because of genetics and environment, poor soul RNG, or something else).

To that extent all technology does is make it more obvious. Basically the average NPC has more opportunities to reveal themselves as such. It's not indicative of a fundamental problem.
