One of the later scripts talks about him inventing that android-body type machine, or at least helping develop it.
But they've already been invented.
There are robots that look like humans, but if you want an upload to experience it as a human body, you would want it to be structured like a human body on the inside too, e.g. by having the same set of muscles.
I made a video last month, which when I mentioned in another thread someone said I should post as a top level discussion.
It's just a ten minute zero-budget thing I wrote in which a girl has a video conference with her dead and backed-up-then-uploaded grandfather. Intended as the first in a series, but later episodes will only get produced if donations come. Later episodes talk more about AI's failures and the political situation with unrest from the living demanding the dead shouldn't have their jobs etc.
Anyway, watch it here if you like, I'd be happy to hear what y'all think :)
