Everything is just silicon oxide gates being saturated and drained and turned on and off in various patterns very rapidly in a way that means something to us. That Fortran/C/C++/Assembly depends on that tiny two-MOSFET AND gate in the ALU to do the AND correctly every time.

Programming languages at the basic level are just an automated way of putting numbers into a calculator, processing them, and getting another number/status/flag back and doing something else with it based on the result.
