I wonder if AI is a technology that will move from "local producers" to a more centralized setup, where everybody just buys it as a service, because it becomes too complicated to operate it by yourself.

What are examples in history where this has happened before? The production of light, heat and movement comes to mind, that, with the invention of electricity, moved from people's homes and businesses to (nuclear) power plants, which can only be operated by a fairly large team of specialists.

Anybody has other examples?
