For one, I think it would be immoral to create an actual intelligence to work for us. With a Human-like intelligence, we’d have to assume that it’s conscious, as we have no way of determining the opposite. We’d essentially create a caste of digital slaves.

That aside, I think the potential for abuse is far greater than any benefits. Making the human mind a replaceable thing, and thus diminishing the value of a human, would be incredibly dangerous. Right now, people in power can’t keep that power without some level of human support. Humans can employ their free will to rise up if need be. Giving that up would not be worth the cheap doctors.
