A fair amount of ML/AI innovations came out of the market in general. Neural networks are a useful tool to solve a variety of problems... LLMs specifically were a more recent interesting market to develop but I've yet to see anything that could give a market player a real competitive advantage. It feels like we just invented a new hammer and now that we know how to build it it isn't that hard to build one yourself. The all purpose hammers are, of course, unreasonable to build - but those don't seem to be that useful. I don't really need Claude to be able to generate sonnets when I'm programming so I think specialization is the place we'll see genuine markets form.
