Quibble: That can be read as "it's approximating the process humans use to make data", which I think is a bit reaching compared to "it's approximating the data humans emit... using its own process which might turn out to be extremely alien."
Then again, whatever process we're using, evolution found it in the solution space, using even more constrained search than we did, in that every intermediary step had to be non-negative on the margin in terms of organism survival. Yet find it did, so one has to wonder: if it was so easy for a blind, greedy optimizer to random-walk into human intelligence, perhaps there are attractors in this solution space. If that's the case, then LLMs may be approximating more than merely outcomes - perhaps the process, too.
That’s one giant leap you got there.
That the probably that intelligent life exists in the universe is 1, says nothing about that ease, or otherwise, with which it came about.
By all scientific estimates, it took a very long time and faced a very many hurdles, and by all observational measures exists no where else.
Or, what did you mean by easy?
We know how long it took. We have a good idea when life started, and for almost all its history, it was single-cellular. Multi-cellular life is relatively fresh, and on evolutionary time scales, the progression from first eukaryotes to something resembling a basic nervous systems to basic brains to humans, was fairly quick. We have many examples of animals alive today from every part of the progression, and we know they actively use it. We know how natural selection works, that it makes small moves, and that each increment has to be net non-negative in terms of fitness (at least averaging out over populations) - otherwise it would die out instead of accumulating.
All that adds up to, yes, it's surprising evolution stumbled on our level of intelligence so easily.
