AI can’t solve everything because, although most things can be described and explained. Most other have to be experienced. And even though something sounds nice in text, once experienced we can say if it’s good or not.

For example, an AI can create a recipe that sounds good, but it will never be able to ground those choices on experience. Only through other people’s experiences combined, which might not be great in the end. And it won’t ever produce and adjust it based on its experience.

The same for a lot of other things that AI is meant to « replace ».
