AI will be more harmful than helpful than a very big and unexplored (for them) codebase for them.

Moreover, playing with code which fiddles with hardware directly is neither simple, nor easy, nor fun.

Big is what AI good at.

What exactly codebase is unexplored in article? Patches? Just load them in context. Linux is already in model as well as nix and hardware specs.

AI is good in search and playing(constrained synthesis) over hardware, Linux and configurations specs. Not fun thing.
