I suspect we will invent bottlenecks for ourselves. There is already so much bureaucratic nonsense involved in knowledge work. For example, in a lot of states for a lot of purposes, a document is invalid if it is not notarized. The notary doesn't really add value in a market sense, we have just decided that you need to go swear in front of another person that you are telling the truth or that the document is genuine. Is it really that much of a stretch to imagine that there will be a human review requirement for lots of things in the future, even if completely irrelevant (or actively detrimental) to the actual work?
