That is not what's happened at all. That's the entire point of the discussion. The robots aren't as good as humans, they can't follow specs or instuctions as well, and their output is markedly worse than human output in a lot of ways.

The only difference is that the robots are faster and don't need rest. And we're discovering now that that is not good enough.
