I'm not very clear on what you think a job is for. I understand a job as a way to trade your service for money and the point of money is to exchange it for other people's goods and services, like the kinds of goods and services we need to not die starving in the street, and are incredibly inefficient to provide all by ourselves. Or to send our kids to college. Or to pay our taxes so that the government can continue to provide its services. Etc.

I mean if you're a programmer and want a job fighting cancer, maybe pick up some ML skills and find a way into that industry. But short of getting your PhD in medicine or a law degree fighting injustice, we're all just a different sort of coal miner providing the things society needs to keep chugging along. And there's no shame in simply being a productive member of society. As far as societies go, we're better than all that have come before.
