Let’s imagine that AI will become cheaper and more efficient, it will not differ from humans in terms of the quality of its work, it will replace almost all intellectual workers, and only the operators of these AI models will have jobs, that is, one person or several people monitor the entire office of AI workers for a small salary. Yes, the AI bubble will burst, but the problems of ordinary people will only get worse from this, jobs will not return, no, automation will continue anyway.
Is it worth retraining as a mechanic, plumber or something like that?
Like telephone switchboard operators, travel agents, and knocker uppers before you, we will adapt. PCs themselves upended almost every industry as recently as the 80s and 90s. Even if the job is to operate AI, the job will exist and they will pay to train you to do it.
