No, I agree with Roko. Some people would probably want us. It's just that we'd be consumption goods rather than capital goods.

Just like kids, really. Most 1st Worlders don't have kids because they are good little workers, they have them because they make them happy. The few dozen cryopreserved people would be a scarce commodity in a world with very few scarcities.

Obviously this would only happen in a nice post-singularity world, or a weird future in which advanced nanotech comes before AI.
