Actualy, how ignorant you are in this area.

Problem solving memories builds from feedback of successfull projects. Society of Mind does a great job explaining this.
Consciousness becomes more suffisticated as more problem solving memories become more abundant and suffisticated.

Consciousness is memory stimulation and memories being passed around in the brain.
Memories are accessed by outside stimulation notifying parts of the brain responsible for acting on stimulation, who then notify each other and plan what to do from a complicated logic gate based on the number of connections to each part of the brain. This logic gate is the programming. Let's
program a bird. Play a low tone everytime you want the bird to turn left and when the bird starts to turn left drop some food. Continualy delay the time you drop food until the bird turns all the way around. Do the same thing for a high tone to turn right. Next put some earphones on it with a message tied to its foot and you have a remote controlled bird. Now make a remote controlled dog, that'll be fun. How about a human? Cool.

What do you mean incrementally?
Do you mean to first replace the eyes, followed by the ears, next breathing,
etc..., until you reach the frontal lobe where you'll get stuck because by
then you'll have found out you really didn't have a clue how it worked?
That's how I discovered uploading was possible, and as someone who searched
for a way to be physicaly immortal since age 10, after discovering it (age
18) I set to work figuring that last part out. And figured out that complex
information interchange was only feasable by software because wire doesn't
grow and making it do so was to complex and would require to much thinking
time in order to apply it within my life time. So my point is, yea, you can
work toward replacing the hardware of consciousness with another piece of
hardware, but by the time that's done we'll all be dead. I eventualy plan to
sign up for cryonics, but I have very little faith in it.

These replacements you mention memic the original functions. That's easy. Too easy. But, consciousness is not just one part of the brain, and it acts differently than the parts currently being replaced. There will come a time when you have to pass along memories and allow them to change and interact. I doubt memories are stored in little boxes as taught in school. It looks to me as memories are patterned interactions.

It'll happen anyways. There are things you can do in virtual reality you can't do in reality. Just don't unplug me. <s>
