Has AI transformed the economy radically? Yes.
Will it continue to transform the economy radically? Yes.
Will that translate to the model-makers somehow capturing the entire value of the transformed economy? No.
There were a few key moments that revealed this. When OpenAI initially declared "there is no moat," I wasn't sure whether to believe them. GPT 3.5 and 4 were so much better than the competition, it felt like them saying that they had no moat was some sort of attempt to avoid regulation or scrutiny. But then, lo and behold, Claude and Gemini caught up; there really was no moat.
But up until then, while it was clear that there was no moat around OpenAI, it was unclear if there was a moat around big tech. Mistral was meh. Even Meta's were meh. We also had no idea how much these models actually cost to run. It wasn't until the "DeepSeek moment," and especially once these open source models actually started being hosted on third party services, that it became clear that this was actually a competitive landscape.
And as has already been demonstrated, because the interface for all of these models is just plain language, the cost of switching models is basically non-existent.

AI made “basically zero” difference in U.S. economic growth last year. https://www.youtube.com/watch?v=zZHN0-ZNe_4&t=399s
"there is no moat" usually mean "we have no moat" or "we want you to believe we have no moat". There are always moats, like being directly in front of eyes and thumbs (Apple) or having extensive data (Google) along hardware production capabilities, datacenters, and tons of money.
