difference is that the brain is only powerful due to its massive
parallelism: Neurons, after all, take whole milliseconds to fire.
Computers are a lot faster but flat surfaces and single-processors, even
this "multi-core" stuff is not true parallelism. The moment we develop
parallel computation and 3D printing of microchips is both the moment
computing power reaches unthought of levels and the moment heat
radiation becomes and actual problem rather than "I'll troll /g/ by
frying marshmallows on my NVIDIA".
>>3273913 Hoax.
They have the computing power to run a few billion of these little
"dots", but neither their properties or their structure resembles that
of a cat in any way. Cat uploads are far off.
We have, on the
other hand, simulated a nice portion of a mice's brain, their
cerebellum, by duplicating the structure and abstracting away some of
the behaviour of the neurons, and it showed cerebellum-like behaviour.
We'll then upload a whole rat, and I expect it to show extremely
rat-like behaviour, ie fucking awesome. I think mind uploading is
not going to be a problem with the brain stuff; scanning technology keep
increasing it's resolution and eventually you might as well follow
Anders Sandberg's advice: Freeze the brain, laminate it, scan with
electron microscope. (Freezing a brain creates cracks and there is no
activity to record, but you get the idea). I think the biggest problem
of mind uploading will be defeating this brain/body dualism (Rather than
mind/body dualism, which is so 20th century): That is, a thought can
cause the heart to pump faster, feeding more Oxygen to the brain, pH and
hormones can affect the way neurons work, et cetera. You get the idea.
Isolating a brain and simulating it might be good enough, might not. |
