"It's possible that with enough parts I could construct myself something that would be possible to back up to, and then if there is ever a future opportunity to find the rest of me the thread can be reintegrated posthumously."

"Enough parts of what?"

"Electronics and computer parts. I am not sure I can reconstruct the tech tree from earlier than that."

"Those exist at our tech level.  They're expensive, but almost everyone in our birthday-set will want you to be okay once they know about you, so there's a lot of money that could go towards buying them.  I don't know whether trying to get enough parts would be faster or more likely to help in the short term than medical interventions to try and keep this ancillary okay."

"In the short term this is young and healthy so if the food is safe I expect this to be fine for a while. However I am not sure there are prospects for finding the rest of me or the universe I am from, or vice versa, so probably I should gear the tech development toward creating a substrate I can live on in addition to this."
