I think people are over rating how much power AI will consume in the long term. Training a model takes way more power than running it, and once we understand the tech better models can be developed for specific applications. It would be like when Edison was first working on the light bulb and extrapolating the power usage of whatever filament he was testing to every household in the world.

Also, it doesn't have to be corporate profits. Individuals can benefit from AI. There's a structural problem with capitalism, not with this technology.
