I have the impression that patterns I've learned are embodied in
connections throughout my (including the periferal) nervous system. I
think the rest of the body does matter.

If you can keep a brain alive and oxygen fed, why not conserve what's
left of your body as well? I had friends with undamaged brains who
would have survived to this day if their spouses had not agreed to "pull

This "throw away and replace" method has evolved to sustain replication.
It works well for fruit flies, but not so well for sustaining a complex
personal identity. Transhuman, I think, means better brain and body.
An artificial body that keeps me imprisoned in a lab would be a step
backwards. Dialectic maybe, but I think we'd do better to preserve and
enhance as much of the human as possible. I imagine "brains in a
jar"will eventually want a body and even a used "fixer upper" will seem
appealing. So I think your idea has merit. I'd just prefer to include
more of me. -- Thomas
