Your mind is just an emergent property of your brain, which is just a bunch of cells, each of which is merely a bag of chemical reactions, all of which are just the inevitable consequence of the laws of quantum mechanics (because relatively is less than a rounding error at that scale), and that is nothing more than a linear partial differential equation.
People working in philosophy of mind have a rich dialogue about these issues, and its certainly something you can't just encapsulate in a few thoughts. But it seems like it would be worth your time to look into it. :)
Ill just say: the issue with this variant of reductivism is its enticingly easy to explain in one direction, but it tends to fall apart if you try to go the other way!
I tried philosophy at A-level back in the UK; grade C in the first year, but no extra credit at all in the second so overall my grade averaged an E.

If by this you mean the hard problem of consciousness remains unexplained by any of the physical processes underlying it, and that it subjectively "feels like" Cartesian dualism with a separate spirit-substance even though absolutely all of the objective evidence points to reality being material substance monism, then I agree.
10 bucks says this human exceptionalism of consciousness being something more than physical will be proven wrong by construction in the very near future. Just like Earth as the center of the Universe, humans special among animals...
We simulate each of those things from the level below. Artificial neural networks are made from toy models of the behaviours of neurons, cells have been simulated at the level of molecules[0], molecules e.g. protein folding likewise at the level of quantum mechanics.
But each level pushes the limits of what is computationally tractable even for the relatively low complexity cases, so we're not doing a full Schrödinger equation simulation of a cell, let alone a brain.
