    If the human brain is just chemical reactions, why can't we make a cmoputer using this very idea? It would seem a waste trying to make some second rate silicon model when we could make something more like the most powerful computer on earth, the human brain?

    There is research ongoing that is attempting to reproduce the chemical/electrical makeup of the brain. However, the interactions that go on in the brain are still quite a mystery to us, and building artificial biological neurons is still a long way off.

    Neural networks, however, have been succesfully applied for several decades now. A neural network is an attempt to essentially reproduce the structure of the brain (on a vastly smaller scale) using classical computing and/or electronics. Neural netwroks are a fascinating area of research, and even a very simple network can be used rather well for tasks such as signal noise reduction and pattern matching and classification. However, attempts to create networks with more than a few thousand "neurons" have proven unfeasible at this time.

    Regarding your claim that the brain is the most powerful computer on earth, I must disagree. How many floating point operations can you do per second? From the standpoint of numerical calculations, even the simplest hand calculator far exceeds the capabilities of the brain, which is optimized for pattern classification.

    With the exception of neural networks, we don't build computers to replicate the brain; we build them to do things the brain can't.
