> we can harbor optimistic thoughts for scientists, medical professionals, lawmakers and maybe even politicians all around the globe to do the "right" thing to preserve human life in a currently recognizable form

Why do you think that preserving human life in currently recignoziable form is something all of us are optimistic for?

For me personally, this option seems like a nightmare - and I truly hope for a transhumanist future made of humans who have very advantage. Being smart, fit and (relatively) healthy is awesome, which I'm lucky to know from experience. I wish other people would be able to experience it, and then some.
