I think a useful analogy is to think of AI as equivalent to the Steam Engine. Instead of making muscle power obsolete, it provides cognition on an industrial scale.
The hype cycle is real, and there will be, as there was with railroad construction in the 1800s, overshoot of production. Unlike with railroads however, demand will meet supply, and just eat up the compute that's available, voraciously.
The profit margins will likely be lower for the suppliers, and higher for those using AI to build things, in the long run, if they satisfy an actual market need.
