I don't think we tax labour. We tax earnings.

Is labor and ai even a meaningful equivalence? I think not.

Do you mean like humanoid?

A actual tax on humanoids performing human jobs could just be seen as a speed limiter, and, I'm pretty sure that goes directly against everyones goals and the best interest of anyone in that position

I'm unclear about how exactly we tax AI. Do we do it per token? Do we tax the companies that use AI? Or provide AI? Do you tax training data brokers or training/inference compute providers? It's unclear who you want to tax.
