I totally agree that we're just scratching the surface of what AI can do. But I don't think it's what Wall Street thinks it is. It's not too terribly difficult to spin up an LLM, which means it's going to be difficult to set up chokepoints to extract rent.
Though I bet they'll get the government's help with that by regulating AI for "safety." The big guys won't have a problem but anyone else will have illegal programs running.
