Re: What do you do onboard a starship?
Oh, there are things that are much worse.
In Sir Arthur C. Clarke's THE SONG OF DISTANT EARTH, the stars are colonized by "seedships". These are slower-than-light starships carrying a semi-sentient computer, remote control drones, frozen human sperm and ova, iron wombs, and supplies. No living humans on board, or at the colony site.(this was because the technology was not up to the task of producing manned starships, and there were urgent reasons to colonize the stars ASAP)
So the starship arrives, the computer lands, warms up some sperm and ova, uses the iron wombs to bring the babies to term and then uses the drones to raise the babies to adulthood. And quietly disposes of any that have suffered too much interstellar radiation to be viable.
In other words, the colony is composed of human beings raised by robots.
I leave you to decide how maladjusted or inhuman such people would be.
