"Get real"? You're the one indulging in imaginary technology, not me. The
hardware to run a full human upload is beyond anyone's ability to build right
now, and that's why I referred to it as powerful technology. You seem rather
touchy about this for some reason. Oh well. I'm sure you'll get over it.

Terrific! So if you can create this kind of model, why not engineer something
even better than a human brain? After all, human brains are inferior to
machine intelligence in some ways.

Wouldn't a 3D computer help in this regard?

Same here: build one and I will concede that you can upload yourself. A UIM is
infinitely more valuable than an upload, because it will be the last thing
humans ever need to invent. Uploads are merely appeals to the egoists.
Useless hypotheses, etc.:
consciousness, phlogiston, philosophy, vitalism, mind, free will, qualia,
analog computing, cultural relativism, GAC, Cyc, Eliza, and ego.
Everything that can happen has already happened, not just once,
but an infinite number of times, and will continue to do so forever.
(Everything that can happen = more than anyone can imagine.)
We won't move into a better future until we debunk religiosity, the most
regressive force now operating in society.
