Just as a measure of how much expectations have shifted, Artificial Intelligence: A Modern Approach came out in 1995. This is the canonical textbook you would be given if you took an AI course today. Automatic image recognition is barely mentioned, apart from detecting highly structured objects (like people) via sliding windows. No mention of CNNs or ViTs. The state of the art at that time was planning (optimizing some set of steps) and adversarial search, along with some pretty basic NLP techniques.
When did we stop calling it "AI"? That's what it was called in my classes 20 years ago.
Of course, if I had to guess I’d say rolling averages are also “AI”
The terms are mushy, but I'd say any automated statistics count as ML.
Also linear regression analysis is now apparently "AI".
All one has to do is attend stats 101 to become a deity
