Ibraham figures prominently into new reddit/cryonics but no quantum physics or even nanotech needed... just better preservation protocol. He's still assuming personality and memory are IN the brain structure. He takes things beyond the gluteraldehyde process of Sueng and Hayworth, which is interesting. He does deal with uploading but has not written about AI/chatGPT simulator-bots.
