If the AI bubble bursts, it will take everything with it, because the global economy is currently single-handedly kept afloat by financial bullshit and ponzi scheme circular investments into AI.

So when (not if) the AI bubble bursts, we are all gonna be fucked anyways. I guess the best advice would be to learn how to live with less (learn how to cook, don't order food or use precooked meals, stop buying your stupid AI tokens, buy used etc.) and either study what you interested in (even if it is computer science) or if you aren't interested in studying or can't afford it, find another job (ideally one, that fullfills you and can keep you afloat).

There is no "ideal" job, that will guarantee you a stable future, so the best strategy is to just do what you are interested in.
