My son at an "elite" university working on AI coding and I (seeing near ready industry use cases beyond the public chagpt examples) talk about this a lot also. This is a "hey, this internet thing may catch on someday" or "I don't know why anyone with need a computer with more than 64k of memory" moment. When these public prototypes get turned into fully functioning field specific tools in 3-5 years, I would guess we will need at least 25% fewer employees in many fields. Good luck to college graduates outside a few elite schools graduating in fields like computer science, law, finance, accounting, marketing, comms, etc in 2030. But as was mentioned earlier, maybe that just takes up the slack for shrinking work force.
