Well, all electrical, chemical, nuclear interactions are purely mathematical. Dig down into the "matter" and the very science you appeal to agrees with the fact it doesn't know what it is. An atom is a collection of electrons, protons and neutrons, and what are those? An electron is a lepton, which is just a word for "this mathematical abstraction partakes in these equations in these ways", and protons and neutrons decompose in a couple more such abstractions. All matter is suddenly abstract math.

Now, in this abstract world of "matter", certain collections of abstractions (COAs for short) called "humans" have been experiencing a vast array of possible abstract interactions with other COAs called "the world". They first tried expressing the feedback of those interactions on a part of their COA called "the brain" with modulating the interactions called "sound waves", and later learned how to encode those into certain states of other COAs called "bits of information", which are not quite bits but COAs called "transistors", which store some abstract "electric charges".

Now the question is: how can capturing those bits and building an algorithm that predicts the next multidimensional array of bits based on the current one REALLY capture the essense of the original underlying interactions and feedbacks the human COAs had, and how can those algorithms experience those exact interactions and feedbacks?
