Obviously if we are interacting over a digital medium then the responses will be encoded as numbers but there is no way to reduce an entire person to a lookup table. Measured output of human behavior can be expressed as lists of numbers but thinking is not the same as the list of numbers, unlike in the case of neural networks where the graph and the network are actually equivalent.

You could represent all the input on different levels as numbers, e.g. all EM waves hitting our eyes, then all the physical output from our body also as numbers, and everything that causes this output from input within is what you would consider to be a lookup table.

What are the dimension of the input and output spaces involved in this idealization? In the case of a neural network there is no idealization. The network is software, it's a number. It's inputs and outputs are all bounded and can be expressed as a table of bounded tuples.
