That's the "bitter lesson", right? Which is really a sour lesson- as in sour grapes. See, Rich Sutton's point with his Bitter Lesson is that encoding expert knowledge only improves performance temporarily, which is eventually surpassed by more data and compute.

There are only two problems with this: One, statistical machine learning systems have an extremely limited ability to encode expert knowledge. The language of continuous functions is alien to most humans and it's very difficult to encode one's intuitive, common sense knowledge into a system using that language [1]. That's what I mean when I say "sour grapes". Statistical machine learning folks can't use expert knowledge very well, so they pretend it's not needed.

Two, all the loud successes of statistical machine learning in the last couple of decades are closely tied to minutely specialised neural net architectures: CNNs for image classification, LSTMs for translation, Transformers for language, Difussion models and Ganns for image generation. If that's not encoding knowledge of a domain, what is?

Three, because of course three, despite point number two, performance keeps increasing only as data and compute increases. That's because the minutely specialised architectures in point number two are inefficient as all hell; the result of not having a good way to encode expert knowledge. Statistical machine learning folk make a virtue out of necessity and pretend that only being able to increase performance by increasing resources is some kind of achievement, whereas it's exactly the opposite: it is a clear demonstration that the capabilities of systems are not improving [2]. If capabilities were improving, we should see the number of examples required to train a state-of-the-art system either staying the same, or going down. Well, it ain't.

Of course the neural net [community] will complain that their systems have reached heights never before seen in classical AI, but that's an argument that can only be sustained by the ignorance of the continued progress in all the classical AI subjects such as planning and scheduling, SAT solving, verification, automated theorem proving and so on.

For example, and since planning is high on my priorities these days, see this video where the latest achievements in planning are discussed (from 2017).

See particularly around this point where he starts talking about the Rollout IW(1) symbolic planning algorithm that plays Atari from screen pixels with performance comparable to Deep-RL; except it does so online (i.e. no training, just reasoning on the fly):

Bitter lesson my sweet little ass.

[1] Gotta find where this paper was but none other than Vladimir Vapnik basically demonstrated this by trying the maddest experiment I've ever seen in machine learning: using poetry to improve a vision classifier. It didn't work. He's spent the last 20 years trying to find a good way to encode human knowledge into continuous functions. It doesn't work.

[2] In particular their capability for inductive generalisation which remains absolutely crap.
