I think we're a lot closer to figuring out how to eliminate biological mortality (or at least greatly reduce it) than we are to any of this AI or brain-upload stuff. After all, there's animals and other organisms out there that are effectively immortal (like the naked mole rat). I believe it won't be too long before we figure out how to eliminate aging in humans, perhaps requiring regular treatments of some sort, which isn't all that different from getting regular teeth cleanings (without which many of us would not have all our teeth).
