It's not a zero sum game, IMO. It will benefit some, be neutral for others, negative for others.
For instance, improved productivity could be good (and doesn't have to result in layoffs, Jevon's paradox will come into play, IMO, with increased demand). Easier/better/faster scientific research could be good too. Not everyone would benefit from those, but not everyone has to for it to be generally good.
Autonomous AI-powered drone swarms could be bad, or could result in a Mutually Assured Destruction stalemate.
It already has resulted in layoffs and one of the weakest job markets we've seen in ages
Executives could not have used it as an excuse for layoffs faster, they practically tripped over themselves trying to use it as an excuse to lay people off
This is literally a description of a zero sum game
You’re so close to getting it and I’m rooting for you
