Pete Mandik shakes his head:
I think our best guide to what we should think about any future beings that surpass us is to think about our current attitudes to beings that already surpass us. On the individual level, I’m not bothered, that is, I don’t feel the value sucked out of my life, by the knowledge that there are lots of individuals that are smarter than me. On the species level, I don’t feel that humans are devalued by the knowledge that other species are faster runners, better swimmers, etc. I think, then, by analogy, we should try to take similar attitudes to any post-humans (mechanical or biological) that outperform us. We should continue to value our own lives on our own terms. And also, you know, root for them, since they’ll be our children.
