I can confidently state that for CRUD web apps, its truly over as in those jobs are never going to command the same wages it once used to.

With the recent models its now encroaching similarly on all fronts, I think the next few iterations we'll see LLM solidify itself as a meta-compiler that will be deployed locally for more FCS type systems.

At the end of the day the hazards are still same with or without AI, you need checks and bounds, you need proper vetting of code and quality but overall it probably doesn't make sense to charge an hourly rate because an AI would drastically cut down such billing schemes.

For me "replacement" is largely a 70~80% reduction in either hourly wages, job positions or both and from the job market data I see it can get there.
