Thats distant future. Farming, mining, wars, police, government, cleaning... Robots arent doing everything. Additionally, these robots are being paid for by companies. If the companies want to give a life to everyone, fantastic! However, Im not comfident that better profit margins translates directly to post-scarcity.

Eminent domain on robotics tech if necessary.

I highly doubt that will happen. There is no politicsl party that currently supports overriding the patent system inorder to provide for the general welfare. And hypothetically if it happens, I now know that any tech I build cant be too useful in case it just becomes a public survice.

China. Which, if it were to happen, as a US citizens I'd move there in a heartbeat.
