Hmm feels a bit trivializing, we don't know exactly how difficult it was to come up with the generic set of equations mentioned from the human starting point.

I can claim some knowledge of physics from my degree, typically the easy part is coming up with complex dirty equations that work under special conditions, the hard part is the simplification into something elegant, 'natural' and general.

Also "LLM’s can make new things when they are some linear combination of existing things"

Doesn't really mean much, what is a linear combination of things you first have to define precisely what a thing is?
