I think it's also that "computer science" can be perceived as having succeeded where statistics failed. And the terminology is frankly a lot more appealing: would you rather "train an AI algorithm", or "fit a model"?
Even the recasting of "model" as "algorithm" has a marketing benefit: models have uncertainty and uncertainty is scary, whereas algorithms are perceived as precise and correct.
Y = Mx + c is simple and common but by no means the only kind of model.
Technically doing a pair of linest in excel and a goal seek to weight the output of each is Ai.
Sometimes the Groundbreaking Ai startup that just raised a gazillion dollars in their 10th up round, is just a plain old basic high school statistical model.
Lots of well-documented success in traditional manufacturing and logistics type things. The "AI winter" wasn't a statistical thing at all - rather, stats have succeeded where logical programming had failed. Branded as "machine learning" or "data science," sure, but I don't recall a time of handwringing over stats failing in between.
(And I've heard "train a model" a thousand times more than "train an algorithm" from data folks in industry...)
I don't think it's failed. But it certainly failed to capture the public imagination. Some people I talk to (fewer now than in the past) seem to think that statistics is old and irrelevant, and that machine learning is new and changing the world. Those people also don't usually have any idea of what they're talking about, but the idea is out there.
> "train a model"
But how often do mass media or industry publications talk about "models" as some kind of new hotness? It's all about "AI algorithms" now.
The terminology usage is especially surreal in the "digital insurance" space [0], where content marketing writers churn out breathless articles about how AI is the next big thing, as if insurance execs didn't understand what a model was!

Of course, the technical details of a text transformer differ significantly from the technical details of a decision tree or logistic regression. But when you zoom out a little, it's clear that many of the same core principles and techniques are used in both cases.
So the content marketers are right in that the next big thing is automating tasks like claim processing. But I find it at least a little bit silly because, at its core, an AI claim processing algorithm is not so conceptually different from a pricing model, and it's well within the realm of understanding for many people on the quantitative side of the insurance business.
I also want to avoid making particular claims or judgments about what AI "is". I will leave that to the futurists, philosophers, and AI researchers.
Graphs may have vertices or nodes. Traversals of a graph may be called paths and walks or simple paths and paths. The length of a path may be equal to the number of nodes or edges in it. The height of a tree may be equal to the depth of the deepest node, or it may be off by one in either direction.
In my subfield, some people talk about strings and substrings while others talk about words and factors. A Lempel–Ziv compressor may factorize the input or parse it into phrases. The Burrows–Wheeler transform, the FM-index, and the compressed suffix array may all refer to the same thing, or there may be 2 or 3 distinct meanings.
I don't think I've ever written a paper without naming at least one new concept and renaming at least one old concept.
I'm not surprised by this at all. There has been an explosion in statistical research really since Fisher. While Bayesian Statistics was invented in the late 1700's, it wasn't really widely used until the 1950's (Fisher coined the term btw). The explosion in computing resources also caused an explosion in statistics, and especially in Bayesian Statistics. It isn't computing leveraging statistics but a symbiosis. Causal Statistics was pretty much non existent prior to the 21st century and major players like Judea Pearl didn't make their ground breaking works until then either.
It should be absolutely no surprise that statistics wasn't in the spotlight before. It was harder to do without computers. Obtaining vast amounts of data was substantially more difficult. Especially with respect to accuracy. Determining causal relationships was essentially a crap shoot.
But this is also a great example of why your theoretical work may not be useful now but can be the cornerstone of modern science a century later.

[1]: Exchangeability, the fact that you can make useful progress in analysing a case by ignoring most of the information about that specific case and instead lumping it into a reference class of "similar" cases, where similar ultimately rests on subjective judgment, other than in a few special cases.
Rather what statistics is about is modeling things that either have imperfect information and/or are probabilistic in nature (yes, there are real probabilities). The point isn't to ignore information (we actually want as much as we can get, which is why we're in the information age and why statistics has exploded with innovation) but to recognize that with observations and sampling that we can extract patterns that still allow us to make predictions without all the information. For example, statistics is commonly used in thermodynamics because there is imperfect information[2], in that we can't measure where each individual particle is at a given point in time. Instead we can aggregate information about the particles and then make aggregated predictions about future states. It is important to note that the predictions are also probabilities.

[2] thermodynamics also involves true probabilities but I think the case is still motivating. We can also use statistics with purely deterministic processes with perfect information, but it is frequently computationally inefficient.
I think this is why computer science has been so successful at co-opting a lot of statistic's thunder. It's reorganizing a lot of concepts, and because everyone is interested in the results (image generation, computer vision, etc) it's getting a lot of adoption.
Amusingly, I thought that the blurb on MCMC the author quoted was pretty clear. That doesn't happen to me often.
