Laziness caused by ugh fields caused by guilt caused by dropping out of their study immediately after getting the fMRI, which explicitly wasn't against the rules but still feels immoral. I also think the probability is low that UCSF and all the people they send the data to will all delete the data. I also don't emotionally care about living forever or being resurrected or whatever, I just have negative motivations stemming from the potential immorality of not trying to save information about my mind that is for whatever reason useful, e.g. useful for future gods to judge me by. Also I think there are already gods hanging around that already have access to information about my brain-mind. Also I think that even if there weren't such gods already then alien gods would still be able to collect the information as they rushed towards Earth and bring it back to any future Earth-born gods. Also I'm skeptical that an fMRI makes a big difference, i.e. I'm skeptical of Paul's approach, especially when compared to options like eating the internet and looking at my writings, including my descriptions of my memories and cognitive style and so on. Basically the scenario where my additional effort makes a difference strikes me as a really unlikely scenario so it's hard for me to care about it, especially when there are way more important things for me to care about. (ETA: I also tentatively believe in a Leibnizian/Thomistic God, Who would know everything about me already. This is mostly disjunctive with thinking that there are already gods on Earth.)
Paul Christiano recently suggested that we can use neuroimaging to form a complete mathematical characterization of a human brain, which a sufficiently powerful superintelligence would be able to reconstruct into a working mind, and the neuroimaging part is already possible today, or close to being possible.
Paul was using this idea as part of an FAI design proposal, but I'm highlighting it here since it seems to have independent value as an alternative or supplement to cryonics. That is, instead of (or in addition to) trying to get your body to be frozen and then preserved in liquid nitrogen after you die, you periodically take neuroimaging scans of your brain and save them to multiple backup locations (1010 bits is only about 1 gigabyte), in the hope that a friendly AI or posthuman will eventually use the scans to reconstruct your mind.
Are there any neuroimaging experts around who can tell us how feasible this really is, and how much such a scan might cost, now or in the near future?
ETA: Given the presence of thermal noise and the fact that a set of neuroimaging data may contain redundant or irrelevant information, 1010 bits ought to be regarded as just a rough lower bound on how much data needs to be collected and stored. Thanks to commenters who pointed this out.
