Earlier quoted context omitted.
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!

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.
