Mgd is right! Simulation is the way to approach AI.
We live in an analog world. Converting analog to digital samples is not
simulation of the brain activity. In order to properly program the
interacting partial differential equations necessary to simulate the
instantaneous response of brain functions, it is necessary to use an
analog computer. Digital inputs can be used to change the function
coefficients, much as the neuron synapses use them. Every probe in the
brain (by Robert Heath in the '70s) produced recordings similar to EEG
signals: analog traces, not digital. It has been done in the laboratory
before.
Now all you AI researchers have to do is to develop a stable million
channel analog computer to simulate a cat's consciousness.
