When a real, creative, pattern recognizing, thinking machine comes into existence, it will not be long before humans are irrelevant. Sentimentality
aside, I think that's a desirable outcome.

One thing I haven't heard yet it the problem of replacing a neuron. I've heard people say, we'll just replace the neuron with a nano-neuron! Well,
first off that'd be hard by itself. The kicker is that real neurons have 1000's of dendrites that connect to other neurons, how do you plan on
matching all those connections? Its stupid to think that you can.
Its funny how people don't seem to have the slightest idea of human anatomy or physiology. I've heard people talk about neurons turning "on" and
"off" and how it could be translated to a cyber-human (whatever you want to call it) as binary 1s and 0s, not that simple. There's this thing that
determines whether or not a neuron fires called an action potential. This happens through inhibitory and stimulatory signals, how would that be
translated into your cyberhuman? Of course, no one seems actually interested in understanding the basics of the human brain yet you have no problems
running your mouth off on how a cyberbrain that doesn't even exist would function.
Do people realize is that all it takes is a supernova or some other event to kill your "immortal" computer body? A gun to the face might not
kill you but a supernova would sure do the trick.
It's all a question of numbers. Assuming the brain is purely physical, which I think is a pretty good assumption, If you can simulate one neuron, you
can simulate a whole brain (maybe not a particular brain; scanning every neuron's connection to every other neuron would be all kinds of hell to do.)
, you just need proportionally more power. And, well, brains aren't getting any more complicated, but machines are getting more powerful. If it can
be done all, it shouldn't take too long. Maybe a few thousand times more processing power than we can currently build?
And while being backed up in a machine isn't real immortality, it's fairly close. You can make multiple constantly updating copies and maintain them
far enough apart that it would take an incredible coincidence to destroy them all. If you're just information, there's no need to be in just one
