I think you meant AI is a subset of ML. Agree AGI is a red herring here. Mostly this is a marketing problem, but the pattern rec., ML, "AI", etc. branding has been shifting around for decades.

This set is far too small to say anything strong about the results, but the problem is interesting anyway.

ML is a subset of AI therefore even though the system is using ML you can call it AI.

Similarly sculpture is a subset of visual arts therefore when sculpting you may claim to be creating a work of art.

I think I disagree in two regards. One that unless we stretch the meaning of AI to extremes, there is plenty of ML that is not AI. I guess that presupposes we sort out the stats vs. ML issues but that's what you get with all these fuzzy terminologies floating around. So it isn't really useful to think of it as a subset, in my opinon.

Secondly, while I know of (mostly historically) a small amount of serious non-ML AI and AGI work being done, it has almost nothing to do with the common parlance to day, which is nearly entirely ML. Is this what you mean when you talk about non-ML AI or is there something I'm missing?

For what it's worth, I'm happy with thinking of them as overlapping, although I do think the AI terminology is almost useless at the moment, and ML is slightly better defined.

I was not referring to the inconsistent way in which these terms are used to sell products and obtain funding for startups, but to their academic definitions.

While most recent successes in the field of AI have been brought about from advances in the subfield of Machine Learning, even today's most advanced AI systems have components that are not Machine Learning (e.g. Alpha Go still requires tree search techniques from "classic AI" to work).

In the definitions below, AI refers to any "intelligent agent", whereas ML refers to the subset of techniques that achieve this through learning/experience/data.

ML: "Tom M. Mitchell provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T, as measured by P, improves with experience E."[0]

AI: "Computer science defines AI research as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals."

Ok, we are bogged down in semantics, but I see where you are coming from. I don't buy the proper subset argument for reasons above (i.e. I don't buy the broading of AI to fit that idea of "intelligent agent", as it includes too many things that don't really fit, imo).

Unless something has changed radically since I stopped paying as much attention there is not actual agreement on these terminologies, at least broadly, in academic circles.

I certainly agree many current systems with a core ML component include other techniques from lots of areas including what you call "classic AI" as well as optimization, etc., but the ML is still the fundamental part of nearly everything recent I've seen. As pretty much every successful system of this type is a hybrid in the sense you mean, I don't find differentiating them from some putative "pure ML" approach very interesting.

There was some good work in very different approaches in the 70s through 80s, but that seems to have tapered off in the 90s really. I'm not very current though and would love to hear of newer interesting things in that vein.
