From my experience (only one of the FAANGs, so far)... It seems to me that FAANGs are the new banks. Like, today's equivalent of 40 years ago's bank job (cushy, well-paying soul-draining job).
So far I'm done with FAANGs. I can get a nice salary, albeit lower, elsewere and still live comfortably.
FAANGs are just not worth it anymore in my opinion.
