Also been wanting to acknowledge this one for several days. I actually know those Vanchurin papers, and in some weird synesthetic way, remember the office I was camping out in when I read them a couple years ago.
Now, wanting to answer Glen’s post, and looking back at them again, I realize I don’t remember almost anything of the details. I am of two minds. On one hand, I generally like Koonin’s sense of questions and the things he wants to synthesize, and these are examples of that. I think it is not just that his impulses are like mine, but that they grow out of a similar sensibility toward the importance of statistics to the affordances of many of our patterns. The other mind says that Claude is being a little too kind. It casts this as an instance of biologists’ gate-keeping and the physicists not having filled in detail and “experimental verification”. I think the “experimental verification” trope is tired now. That’s why there are all those papers in Nature that say “we set out to test whether 1+1 = 2, BUT WE DID IT ON A QUANTUM DOT!!!”. The converse of that. If you have a new piece of math, to organize the statistics of things you’ve already been counting for centuries, more counting will not be the measure of the math’s correctness. I think that, worse, what Vanchurin et al. are doing is, to some extent, mapping terms in a simile-manner. There has been more than a century of this in evolutionary biology, people defining “evolutionary temperature” and “free fitness” and “evolutionary entropy” and stuff of that kind. Some of it turns out to be correct when built from first principles. Other is empty, because it tries to lever _one_ of the attributes attached to a concept up into a map of terms, which the rest of the concept doesn’t respect. I had to sort through a lot of this literature to get some papers published a year or two ago on various information measures for evolutionary dynamics, which were _not_ based on similes, but just on counting, in the normal way. With my quibbles above said, I can still imagine that there is some version of the conceptual merger (learning, large-numbers, and entropy available from the initial conditions), that could push through something along the lines that the abstracts in the papers say. When I see Koonin, I still like to engage him in conversation, because I think he is imaginative and synthetic. Maybe partly because he doesn’t feel compelled to be super-careful about a lot of things. I don’t mind being the one who comes in afterward and tries to sweep up various messes.
