However, people saying that C-suite can be replaced with GPTs don't understand that plenty of people not in C-suite could be replaced or not replaced just as well. Lots of office plankton around with such reasoning skills that I just don't know how their work can bring profit.

I can't decide whether those people are really needed or they are employed so that they wouldn't collectively lynch those of us who'd keep relevance, but wouldn't be social enough to defend from that doom.

The problem with building hierarchies of humans is with humans politicking and lying and scheming with each other, not even talking about usual stuff like friendship and sympathy and their opposites. It's just impossible to see what's really happening behind all that.
