Are you saying no one will have to build houses? No one will need to build roads? No one to drive the trucks? No janitors or waiters/waitresses? Arguably these things just fuel the cycles of consumption. They are actually just as societally impactful as say Elon Musk. Without these things society breaks down. You may not feel like you are contributing as much as you can, but if you look at it you might be contributing more than you think. I feel that way sometimes, but I know insurance is necessary for society and without it who knows what would happen.

Absolutely and I do see the value of anti AIDS drugs, that was not the point. I'm saying value is a subjective thing. Something does not have intrinsic value, things have value to people, and sometimes something is valued so broadly that it is of value to society at large indeed.

It is of course nice to have work of which you personally value the output. But in your case, someone else values your output and pays you to produce it. Calling your work "without value" is thus a bit strange to me.
