Things like going through 500.000 cases containing multiple documents and sorting them correctly can be done with Azure services in 5 hours after a 14 month algorithm training period. It takes 5 people working 37 hours a week 3-5 months to achieve the same result and they will have a larger margin of error than the machine. I know this, because we did the same process as a competition between man and machine.
Getting back to the point, however, everyone loves my department. Part of this is because people aren't really fired due to automation, we solve the freed up resources by not hiring people when someone retires, but the main reason is because we automate boring stuff.
Nobody wants to sort through 500.000 cases manually, so you're absolutely correct, automation can free up humanity.
Some people will spend their time being productive, but the truth is you don't have to. That is, if we manage to take back ownership from companies.
Today western society is build around income tax, and as long as that doesn't change, we're not heading for freedom but for oblivion.
