Oh good lord. If you want to quit a job, quit it. Top tier tech is no different to anything else. OP should have titled this post "How to not realise you're having an existential crisis and respond to it by massively over-complicating a very simple career decision."

Fundamentally this is true, but bringing yourself to the point where you "just quit" is quite difficult.

I think you're ignoring a lot of human things like that a lot developers are quite isolated and working 60+ hours a week. Their social group is quite likely just their co-workers. Especially for new devs who have relocated.

That's a good point I didn't think about. Assuming you are most likely burning some midnight oil at a top tech company, you'd be stressed to keep up a social circle besides your coworkers.

I think that plays a bigger part in it than we are thinking
