I would add that proof of work algorithms (Bitcoin type) where the goal is to endlessly compute hashes with no real computational productivity gain are the real offenders, regardless of which language they're written in.

Most of the implementations for LLMs runtimes I know of are Python using PyTorch. I believe most of the heavy lifting is written in C++ (llama.cpp), though.

And given that a major limitation of bitcoin-hashing is the cost of electricity, I would guess that they're written in a very energy-efficient language already.
