It is possible that AI based HR won't actively be trying to sabotage his company from within. The problem with HR is it's always trying to be active. They can be busy bodies.

Getting cat ladies that are trying to frame their spite toward all the men in the engineering department that make more money than them as useful HR activity to turn off is harder. Being able to spin up and spin down HR has got to be attractive.
