Yes, but if you send the same promt to the same LLM n times, you'll get n different versions of the same thing.
When compiling the same C code (for example) with the same compiler and the same settings n times, you'll end up with n copies of exactly the same binary.
The argument was about deterministic abstraction.
A bunch of devs can hardly be considered an abstraction layer imo.
My argument was that a C compiler is an abstraction tool that deterministically turns the description of a program (in the C language) into machine code. That way people don't have to write machine code by hand.
