I don't mind an extra Brosz colonizing the Centauri system. But it sure as heck won't be "me."
Technologically, it would probably be easier (not easy, but easier) to ship hard-frozen embryos and grow them to full term in artificial wombs at the destination. The hardest part, IMO, would be developing an AI sufficiently complex to raise kids to healthy adulthood. I checked: Fantocinni Ltd. is not in the phone book.

"If yer goddam robots are that smart, what the heck do they need the people for?"
