It's not like managers and executives and PM's are the only people who can prompt an AI. And experienced software developer will be much more effective at using an AI to generate code compared to someone who isn't. So why would we expect the former in the breadline and the latter not?

If anything, I'd be more concerned about the leadership team being out in the cold. Why do I need a PM, or a manager, or a CEO if I can ship products myself?
