I think AI is a term that's confusing. I agree that lots of things our PCs can do and have been able to do for ages is nowadays described as AI. For example spell check that adds words we type frequently could be described as AI. The term 'machine learning' is much less emotive. AI has anthropomorphic implications that all too easily lead to paranoia about skynet...........

Lots of uses of AI are what one might call 'conditoned responses' - the machine sees 1000 examples of xrays and then responds when it sees a new one that matches.

It's probably obvious that i'm no expert but the term AI is a broad catch all and these days seems to be a 'sales plus' when its the mixture as before
