I think it's most likely we won't get "upgraded", but rather cloned into computers. I think the essence of ourselves, the original, will stay within the vessel of our body - and doomed to the flaws therein. But, our personalities will be able to be carefully cloned (likely using a ton of questions fed to AI, or otherwise) in essentially infinite AND limitless computers. It's a scary thought, to be sure. That, no matter how close a computerized copy of me is to me; I'm still stuck in this body, in this own brain, and its inevitabilities.
