you aren't truly in control of your compute in the cloud, and if you came to become reliant on ai, the cloud company could simply turn it off for you and you'd be shit outta luck. Unlike a regulated utility like electricity and water, where you cannot be discriminated against based on how you use said utility.
Therefore, having the ability to run local ai is a good thing. Currently, hardware constraints have kept it out of most hobbyist's hand, but i am hoping that will change soon enough (within 2-3 yrs).
The mega corps are looking to regulate ai such that individuals cannot run their private ai themselves, so that they can become more effective a monopoly. That's why it is crucial that ai is not regulated, but companies providing ai.
