A "failure to misunderstand" is a fitting turn of phrase.
People not only ignore second order effects, they also don't think about what would actually happen when a "winner" really "took all".
While AI is a tremendously useful technology, business types wildly misunderstand it and its consequences. Greed eats brain.
You got me on that one, geez! I'm not going to edit it though because I think you're right. Nobody really knows if there's going to be a winner-take-all or not. During the arms-race portion though people are definitely acting like it will be that way. But watching how fast models catch up to each other it's not obvious it will play out that way.
