Re: changing course, as long as your generation ship accelerates for more than one human lifespan, your future generations of involuntary colonists aren't going to have a lot of options besides going along with it. The choice wouldn't so much be "keep going or veer off and colonize a closer star system" as it would be "keep going for another 800 generations or veer off and colonize a closer star system in another 80 generations". I mean, there's probably no way to stop them from making that choice, but it's hard to see anyone caring whether their nth-great-grandchildren die with one or ten millennia left on the trip.

If the ship accelerates for the first 100 generations, the 2nd generation likely still has every chance to target a different planet. I don't know which generation would be the last, but I'd need to see actual math to believe that it's strictly only the first generation.

One more consideration is targeting data. Do you even have another target or the sensors to find one ? The means of detection for a suitable planet or even just a good solar system, where you build a bunch of habitats might require huge telescope arrays or even something like a special telescope that uses the Sun as a gravity lens source.

Might be out of reach for even a massive generation ship.

Then you have a natural upper bound on the amount of amenities etc, because if you provide too much, 1000 generations can probably use it to try and find another target.

I'm sure you can keep making the situation more and more specific, but that's not going to increase your chances, or make the whole thing morally acceptable.

Well if the goal is to settle a new planet or solar system then I guess it is working fine ?

		I have no idea how to interpret this answer in the light of the arguments I've been bringing up, it doesn't feel like you're engaging with my words. The goal is not to settle any random new planet or solar system, so no, it's not working fine.
