I think the problem is people forget the possibility we will ourselves slowly turn ourselves into machines as well. Robots will become less metal/wires and will eventually look just like us, so it seems inevitable we'll be able to live on forever and not have to deal with human limitations like aging, eating, not being able to see the full light spectrum, radiation, oxygen, etc.. Dammit now I feel like reading some Issac Asimov books.
But yeah it seems likely AI will happen, not sure why but I feel like we'll be able to still program a fail safe to keep them from turning on us. All I know is I want to be around to see all this, lets hurry up science I need eternal life, or at least let me stick around for a few hundred years more
