We can dare to dream of the stars again, if only we can achieve this small thing.

This is the first I've ever heard of this and it's an interesting concept. We do need better forms of space propulsion but we should at least test the waters in our own solar system, so to speak. It's been 43 years since we landed on the moon and we haven't done jack shit since then. It's almost as if we need the threat of a nuclear war to get anything done. Pathetic.

We're, of course, talking in hypotheticals about the future.

The deepest purpose of ethics is species survival. So whether act essential to species survival can be smoothly undertaken within the ethics system is the measure of the ethical system. The ethical system is not the measure of whether this act should be undertaken. That a act essential to species survival might seem unethical shows the system of ethics is deeply, perhaps fatally, flawed. It means when the foreplay is over, and the chips are down, the system of ethics is found to hinder rather than further its own most fundamental reason for existence.

Generation ships are not only for survival, but for exploration. It would be a totally different situation if we had no planet to return to. If we do, generation ships are insanely unethical. What are we if not the sum of our choices? Being born on a ship to continue a mission, just as Hovik said, is a vast limitation of personal choice, which is why it's unethical.
