Survival didn't involve a CS job at FAANG until very recently.

Capitalism is not a new evil, you're absolutely right. It's just the system that, according to our current framework, came after feudalism, which came after something else.

the point is that actually seeing the changes in systems as consequences of massive technological change is likely directionally correct and it is not clear whether current capitalist logic survives the AI era.

What is a CS job at a FAANG in practice? Many hats. For example if you work at Netflix on content delivery, you are the modern version of someone involved in the boring logistics of theaters and plays. If you work at Google on search, you are the modern version of a librarian establishing ways to catalog information. If you work at say facebook, you are the modern version of a propagandist or even town crier perhaps. In all these cases, these workers were delegating their basic survival needs to other members of society. Ancient Rome even had its own slop bowl restaurants not all that different than what you see in SF today, and many ancient romans did not cook for themselves but instead traded credits gained from labor elsewhere to eat at these establishments. No different than lunch time in SF today.

The actual tasks being done have always been done even if the technologies used to do the work have changed and the work itself looks a little different. Our base needs have not changed. We are the same apes bound by dopamine. The functionality we require is pretty old. There is probably little we experience that is truly "new" compared to what one might experience in a classical civilization.

Capitalism is far more ancient than feudalism. Phoenicians were famous capitalists, likewise most any group of people involved in trade. Trade and accumulation of capital representing labor is ancient.
