That’s a cool and scary thought on human thoughts. And the afterlife of the immortal brain without the human aspect of it. Essentially the person dies but the contents of their brain lives on. It seems to not “solve” the issue or provide the much sought after life after death. But it seems to be heading in the right direction. I’m not really qualified to speak on this topic but I’d say if you can salvage a healthy brain and put it into a new body maybe that would work ( without a lot of tweaking and research and stuff beforehand and to go along with the process).
