Lets imagine that the way computers think and the way our brains think aren't actually very different at all.
What frame rate do our eyes get?
Or do we get such a high frame rate that our brain can't perceive them all?
What resolution do we see in?
Does our brain see in pixels? When it comes down to the very smallest visual light wave that our eyes take in, is it circular or square?
How does memory work? It is said that different parts of the brain handles long term and short term memory. How does short term memory eventually shift over to the long term side, almost as if moving a file to another hard drive? How do we retrieve these memories?
How many bytes can our brain hold in terms of information? Its probably far more than our life span has room for, but its obviously not limitless, is it? Zettabytes? Yottabytes? Is it possible to cram enough knowledge in to the brain to the point where it becomes full? Would it, like the computer, stop receiving new information? Slow down? Crash? Delete old information?
Try to ponder the answer to these questions the best you can. Also add any more similar questions if you'd like.

"The human brain contains about 50 billion to 200 billion neurons (nobody knows how many for sure), each of which interfaces with 1,000 to 100,000 other neurons through 100 trillion (10 14) to 10 quadrillion (10 16) synaptic junctions. Each synapse possesses a variable firing threshold which is reduced as the neuron is repeatedly activated. If we assume that the firing threshold at each synapse can assume 256 distinguishable levels, and if we suppose that there are 20,000 shared synapses per neuron (10,000 per neuron), then the total information storage capacity of the synapses in the cortex would be of the order of 500 to 1,000 terabytes. (Of course, if the brain's storage of information takes place at a molecular level, then I would be afraid to hazard a guess regarding how many bytes can be stored in the brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"

Not sure how reliable that source is there.

72fps. easy way to test is to use a crt monitor. at 60hz you'll see flicker, but at 72-80 you wont.

That makes me wonder about what being alive is.
Scientifically, we're nothing but sacks of flesh, blood, and bone with electronic signals being sent through it.
What is alive?

Theres no need to get emotional over this concept, of course. As long as you have the conscious ability to think and reason, living isn't dull.

Life is confusing. No wonder people have spent so much time on "the meaning of life".

Maybe in the future they'll learn to clone people and they'll finally figure out exactly how the brain works.
What are memories? Are they a cell in your brain, or a chemical, or an electric impulse or something else? I don't know how the brain would store that much and be able to recall things.

Nonsense. They've already figured out most of it.
Also, cloning has been around for what, a full decade? We just don't do it because the public BAWWWS about how it goes against ethics.

But not really cloning a human brain :\
I mean, they clone meat for eating..

Replicating the exact brain cells is practically impossible.
We can clone humans, to have the exact DNA and looks as the cloned. But they would learn and experience from scratch.

MY guess is its similar to vinyl. Our brains have a recored pattern, our memories, etched into a certain part of it and its the only brain with that pattern. So replicating a single mind is impossible just like its impossible to make an identical vinyl without etching music into it.

Replicating a biological brain with all the data/personality it contains is not likely to be possible until we have the technology to create and place attoms together from scratch. Similar to the 3D printers that are recently coming around, which can 'print' complex 3D objects, except on an atomic level. At that point we would be able to analyze the exact position and number of atoms, map all that data, and 'print' a brain that is an exact copy.
What's more likely to happen first is the ability to store the human brain electronically with hardware.
Either one of these would lead to theoretical immortality.

Before that happens WW3 or Global Warming will have killed us :S
