Maybe it's a good idea for SWEs to consider using LLMs to train themselves into new careers -- just in case.

Most other "knowledge" professions -- by which I mean teaching, programming, some engineering, and the arts -- are even further along into obsolescence. That said, you can still use the knowledge gained in a knowledge profession to convert into a more hands-on profession. We might have a bit longer before humanoid robots destroy all hands-on job opportunities as well. Once that happens, every person will be equally poor and destitute.
