>Putting the current ethical concerns aside. I find this absolutely fascinating. How long until the technology is perfected and some form of immortality is reached? No expert here, but first you are limited by cellular decay. If we can reverse engineer the aging gene and apply it to the brain, you might be right that we can stave off cell death by a lot. Then there's alzheimers and other forms of dementia, which the aging thing probably won't fix. Even if you cure alzheimers, you still have memory loss. So then we'd have to invent some type of memory therapy that defrags the brain and allows consciousness to continue to access a healthy memory bank. Not sure if you'd be able to maintain new memories, slowly lose old ones, or what. But then we could preserve consciousness. So once you perfect either controlling human memory or at least defragging it so the brain doesn't go crazy or develop dementia, you now have an immortal brain. As long as it has access to the therapy it needs, maybe could live for forever. Am I wrong here?
