What do you think about this analogy?

A simple process produces a Mandelbrot set. A simple process (loss minimization through gradient descent) produces LLMs. So what plays the role of 2D-plane or dense point grid in the case of LLMs? It is the embeddings, (or ordered combinations of embeddings ) which are generated after pre-training. In case of a 2D plan, the closeness between two points is determined by our numerical representation schema. But in case of embeddings, we learn the 2D-grid of words (playing the role of points) by looking at how the words are getting used in corpus

The following is a quote from Yuri Manin, an eminent Mathematician.

https://www.youtube.com/watch?v=BNzZt0QHj9U Of the properties of mathematics, as a language, the most peculiar one is that by playing formal games with an input mathematical text, one can get an output text which seemingly carries new knowledge. The basic examples are furnished by scientific or technological calculations: general laws plus initial conditions produce predictions, often only after time-consuming and computer-aided work. One can say that the input contains an implicit knowledge which is thereby made explicit.

I have a related idea which I picked up from somewhere which mirrors the above observation.

When we see beautiful fractals generated by simple equations and iterative processes, we give importance to only the equations, not to the cartesian grid on which that process operates.

Isn't "emergent properties" another way to say "we're not very good at understanding the capabilities of complex systems"?

It's more specific than that. Most complex systems just produce noise. A few complex systems produce behavior that we perceive as simple. This is surprising, and gets the name "emergent".

The authors haven’t demonstrated emergence of LLMs. If I write a piece of code and it does what I programmed it to do that’s not emergence. LLMs aren’t doing anything unexpected yet. I think that’s the smell test because emergence is still subjective.

They weren't trying to demonstrate it. They were explaining why it might not be surprising.

Not quite. Complex systems can exhibit macroscopic properties not evident at microscopic scales. For example, birds self organize into flocks, an emergent phenomenon, visible to the untrained eye. Our understanding of how it happens does not change the fact that it does. There is a field of study for this called statistical mechanics. https://ganguli-gang.stanford.edu/pdf/20.StatMechDeep.pdf

How could they not? Emergent properties are unavoidable for any complex system and probably exponentially scale with complexity or something (I'm sure there's an entire literature about this somewhere). One good instance are spandrels in evolutionary biology. The wikipedia article is a good explanation of the subject: https://en.m.wikipedia.org/wiki/Spandrel_(biology)
