The downside to all of this is how disruptive it will be. Not everyone can program robots (robots will be largely built and programmed by other robots). Not everyone can run a small business.

When the dust settles, the world would consist of pre-industrial tribes run by communist war lords. The left’s dream for the world would be realized.
