It’s interesting to me that in these conversations, some people think it’s inevitable that intelligent life will want to colonize other systems (or die trying) while others think it’s impractical.
But I think both of these opinions come from human-centric reasoning. A species that could hibernate may be able to control hibernation through technology, so a ten year journey wouldn’t be as complicated for them. Other species on earth simply don’t have the curiosity to explore the way humans do.
Speculation about alien intelligence is interesting to me, but I imagine it’s a lot weirder than we think. Especially around topics adjacent to intelligence, like curiosity, motivation, and cultural values.
