Can you actually imagine life where innate talent and learned skill had no value outside of social posturing or self-gratification?

Pretty sure I'm there already.

Where a Godlike machine secretly planned out your life according to some formula of ideal living?

Sounds comforting.

Where no-one suffered or died at all unless they chose to

Yes, a thousand times yes.

and real power is essentially non-existent?

Hmm. If I could only gain happiness from having power over others, I would be forced to consider myself as evil. That aside, in these post-singularity utopias I could have an arrangement with other people where we took turns, or gambled. Or I could lord it over a nation of entities that looked and acted like humans but weren't really.

Is that a better deal for me personally? Depends on whether I'm powerful at the moment. But it's certainly an improvement for people on average.

Where you'll be, in all likelihood, locked into a computer simulation while the real world is being torn apart for materials to increase your jailer's intelligence and extend its lifespan?

Agreed that this is bad. Post-singularity utopian AI should not do this.
