The question of ownership is huge and I think still underaddressed, even after some good work like the referenced Lena, or Tom Scott's "Welcome to Life: the singularity, ruined by lawyers" [link] . I was realizing a couple of weeks ago that if you do believe all the materialistic things cstross outlines, that a solid argument can be made that it may be never rational to upload your mind, on the ground that there is simply no circumstance I can imagine where you will "own" your own substrate.

For a while I thought a rich person could do it, but then I thought about the entire supply chain involved in creating any brain scanner and subsequent computational device, and the amount of hardware left out in the real world where others can affect it, and I realized, you just can never assume that you are doing anything other than flinging yourself irrevocably into a locked box that is not under your control. Even if a rich person thinks they funded the entire project, brand new software, brand new hardware, there are thousands if not millions of points where either mistakes or deliberate sabotage for control may have been don
