Non-AI-assets: yup, this is sensible. AI is a signal of being unconcerned about being seen as a cheat, absence is good.

Non-AI-code: forget it, you won't be able to avoid it in your libraries, and you won't write the whole engine from scratch.

It's possible to write a whole modern engine without it, but you won't, you'll spin wheels chasing features and never ship.
