The author seems to have written the article on the assumption that it will be humans figuring out a brain upload mechanism.<p>While his time frame estimates might be sound given that context, I&#x27;d argue they&#x27;re wildly inaccurate given a more likely scenario: such things will be brought into existence first via a super-intelligent agent, if at all.<p>If that proves to be the case, the time frame for brain uploading becomes roughly bound to the advent of AGI. When that happens, the same entity capable of creating our brain upload mechanism would likely be capable of endowing humans with effectively immortal bodies just the same.<p>In other words, technology like this is almost certainly going to be part of a post-singularity world (assuming there is a singularity in the first place), and who knows what that will look like.
