I'm struck by a quixotic idea where future-companies return to a "X years service for a gold watch and a pension" approach. I don't actually think it would happen though.

A not-too-dreary idea: Perhaps the the beginning of the career-arc will change in terms of how quickly developers need to focus on code-reviews and diagnostics (of LLM output) at the expense of "read the docs and follow a guide." Of course that depends on a cultural understanding that LLM output must be checked, and that may take some major industry to become accepted by non-developer bosses, if ever.
