What are you talking about? AI is way too broad of a term to be talking in generics like this.

Are you talking about ML models that help with diagnosing patients, find new cures, find new planets, upscaling, motion prediction, self driving cars, image generation, object detection, text generation (ChatGPT), audio generation (music, voices), etc?

If you’re talking about some “AI” that’s meant to replace a system where we already have a simple solution (like a rain sensor) then, yeah, training a model on that is not worth the effort.
