Ideas on AIAt the level of molecular biology there is no counting or numbers - only exact pattern-marching of unique structures or "symbols". This means that all signalling is not digital, but symbolic, where each message is a unique symbol - a unique pattern. It uses a gradient-based instead of frequency-based regulation, without counting. One of the implications is that the world at that level is pure-functional pattern-matching (enzimes and proteins) with asynchronous message-passing and gradient-based feedback loops. The brain is an "analog" device, not digital. There is no numbers outside human mind. Neurons, presumably, are propagating "weights", not bits, creating unique patterns in a mesh by firing specific sets of neurons. Like a cell, its language is of "structures" or unique symbols not numbers. This, perhaps, was a great insight behind Lisps - symbolic computation by using the same list structure for code and data. Not bad, yeah?
