We need cloning bays, and extremely hardened ships. Don't send a person, send a blueprint and some way to raise and teach a first generation. We don't have to get there ourselves as long as our "children" can.
Minor detail- who's going to raise the children in this sci-fi scenario? You're going to have a whole generation of children brought along as frozen embryos, brought to term in artificial womb tanks, then fed and cared for as infants by robots, raised by robots, taught language by robots, getting the "where do babies come from" talk delivered by robots (in this case, they get a really freaky explanation), going through a rebellious teen phase ("What are you talking about? I do not dress like a little slut! All the cool girls dress like this! God! You're so lame! I just want to hang out with my friends at the supply depot! You never let me do anything fun! I hate you Matriarch-371B! You're a terrible parental simulacrum!")... most humans do a terrible job at this, do you really think an AI could handle this kind of stuff? Any AI capable of raising an infant to an adult and doing a good job would find interstellar exploration trivial by comparison.
