At the end of the day, the processor can only do Turing operations: assign values to variables (registers, memory locations, storage), loops, bitwise operations, and conditionals. Whether the source code is python, java, or lisp, it has to compile or interpret down to machine code ultimately. Likewise if the running software is a word processor, DOOM, or an LLM, at the end of the day it will be executed by the processor using the three operations. Lots of other fancy hardware and software may accelerate things but ultimately it is those ops that are the running code. The rest is many wonderful conveniences and abstractions.
