"I could write in brainfuck with ai"

Well, go on and do the experiment! Perhaps LLMs can right code as well in BF as Python but I don't recommend it because hallucinations are really hard to notice in BF.

If you are going to worry about high level computer languages and AI, you are going to have to start with getting to grips with machine code and assemblers and that. Once you know how say some Python code ends up being processed by your laptop CPU(s), then you will know when BF might be best!
