But please don't worry too much about the example I used, it's just a tangent. What's wrong with my argument about closed-source AI always having an edge?

(Actually, I can think of one possibility - when a company has an incentive to open-source AI in order to commoditize their complement. Content aggregation companies might want to commoditize content-generating AI in the same way that hardware companies wanted to commoditize software. Same argument holds for Nvidia maybe - what better way to sell silicon than to make sure there are a lot of really useful open source models out there to take advantage of it?)
