(this might not be a great response since i'm at work right now)

when you say you'll be moving into a clone what age is that clone?
if it's an adult clone (or rather a clone that isn't an embryo) you'd surely have issues growing it. how would you grow a human without it becoming "alive" in the sense that it develops its own personality and memories. if that's unavoidable then again, you've just taken another persons life (your own in a crazy way, but still taken a life)
so, say you dont go that route then you'd be doing it t a baby you.
babies probably do have memories, but the brain (physical storage) would be continuously changing and these memories would get lost

cybernetics is when you augment yourself with physical machines right? like integrating a special contact lens that does stuff
yeah it's happening, experiments and research is being done on such things, but would you really say that humans are becoming extinct? technology augments us, it doesn't change our genetic code, therefore it's not physical evolution
genetic modification to bodies or designer babies doesn't make humans extinct. we'd still be human. it's not like we'd get a drastic change from it (like the whole dinosaur evolved into a chicken). or if we did and that change was for the better then humans as we know it would be extinct.

evolution is what you say it is. adapting and mutating to survive. now... take that definition literally. when you look around outside at the city what do you see? buildings? cars? roads? it's evolution in thought. the way people think changes, it adapts to the surrounding and it adapts the surrounding to it.
