Either it's ChatGPT or it's all the layoffs. You don't need StackOverflow if you're not working
Thus, if you don't want to get laid off in the next round, stop using StackOverflow ;)
I can, however, come up with scenarious where company would choose either cohort for layoffs (so you are helping engineers from other companies on company dime?).
Still, I was completely tongue in cheek regarding causation and mostly noting that it is unlikely to be any correlation there.
