If you want to argue, as I think you do, that there are no new ideas other than new combinations of old ideas, then you have to explain where the old ideas came from. It can't just be combinations all the way down. At some point, some initial set of ideas must have been created where none existed before otherwise we would have nothing to combine. After all the combinatoric closue of ∅ is ∅.

Ultimately any claim that there exist only combinations of old ideas must tackle this chicken-and-egg problem convincingly. For example- explain art. There was no art until it appeared fully formed and out of nowhere in early anatomically modern humans' dwellings (Neanderthals also had art but it was simpler and it is subject to the same chicken-and-eggness). So where did art come from? What pre-existing ideas were combined to bring it into existence from non-existence?

Btw, since I've had this conversation before- if the answer is that we looked around us in the world and saw things; yes, but we didn't see art. Where did art come from? Where did the idea come from of abstracting shapes and colours so that they resemble the shapes and colours of existing things, without actually being those things, or being composed of pieces of those things? How about numbers? How about writing? How about all our technology and science? Where did those things come from? What did we combine to create them?

Obviously I think that the argument that there are only new combinations is wrong: we are a creative species. We can create new things. Somehow. It would be very interesting to understand how. We have not yet created machines that can match us in that and we can't understand the "how" by studying the machines we have now. By denying the mystery of this our ability, by denying that it is a mystery, by dismissing it and accepting any facile explanation that presents itself in our current era -it's god, it's nature, we're like LLMs- we are making ourselves a great epistemic disservice, denying ourselves the chance to find out what it all means, to understand what kind of creature we truly are.

> then you have to explain where the old ideas came from

Its fairly plausible that the original ideas could be sensory gradient-triggered impulses in simpler creatures' proto-minds that (physical and cultural) evolution has gradually built up through more complex neural machinery supporting more complex representational language.

> where did art come from

Similarly, its not a stretch to see art as built from earlier attempts at representation in physical space - starting with mundane attempts at information exchange by colony insects or pack creatures. The breadth and depth of expression has evolved alongside more complex neural machinery and greater variety in media through technology. There's a hidden lineage in creatures' expressive capabilities that may not be evident when we look at a Caravaggio today, sure.

There's nothing terribly chicken-and-egg about these issues (though the resolution is the same - "chicken" and "egg" co-evolved through iterative selection pressures, one didn't precede the other).

All that said, I concur that its a fantastic and mysterious topic to unpack, but it doesn't follow for me that humans are anointed as uniquely "creative" or that there's necessarily something metaphysical at play.

Truly new ideas are, say, 0.01% of all 'novel' ideas, with the rest being rehashing or recombinations. And even then, the truly new kernel of the truly new idea is some small fraction of the whole thing. Like Einstein's theories of relativity, they were truly fresh, but mostly had to recombine existing work in 'novel' ways.

So it's not there are zero new ideas, but so few compared to the whole of the intellectual domain, that we can say 'there are no new ideas under the sun' and be basically correct to within a small rounding error. And AI is sufficiently ingenious to serve the needs of the vast majority of humanity, even though we'll still need to find/cultivate/inspire some new genius humans if we want to have more truly new ideas in the future.
