A lot of them are much easier if you just look for the one that did hands well. That's the human one.

We don't live in medieval England.

You would be consigning yourself and all future generations on the ship to slavery in a eugenics cult from which there is no escape. There are a small number of people available to fill limited roles, so you must hold that role for your entire life until there are enough trained replacements to do it. The replacements would also not have a choice and would begin being trained for that role from an early age. Since the ship has a maximum capacity for people all breeding would need to be centralized and required of women. It's a problem if people live too long as they are taking food from the younger, healthier generations; so you might even see ritual suicide in elders being required.

Man, the last time I answered a question about generation ships was 13 years ago. It was a joke that went like this:

>Would it be a sleeper ship or a generation ship?
>If generation ship: Fuck no.
>If sleeper ship: Let me sleep on it.

There is a long way to go between now and AGI being reality, don't be confused by early successes. We are still a long way from anything autonomous and self-referential. In the time it's being built AI will be specialized to bootstrap new industries and boost human productivity. You can also directly contribute to the training of such systems if you know how to build front end systems for gathering human feedback or interpret output of systems to improve on their effectiveness.

We do need those things, they likely will not happen without it being bad for quite a while to the point that those resisting it have no choice.
