This isn't about physical labour vs mental labour, it's about the dynamics of delivering a product vs contributing to a community.

For example, a software engineer is like a car mechanic or a coal miner. None of those are anything like a mathematician.

The person you're rallying against isn't me, it's an imaginary hypocritical person which exists in your mind. I do mental labour, I welcome AI developments hard, and I still think TT is 100% correct.
