Sorry, but all of this strikes me as a very naive take on where AI is headed. The only reality I can see happening is that it just gets used to peddle even more ads to people while harvesting every single scrap of data possible on everyone while replacing large swathes of the population with cheap labor for the ruling classes.

This utopia you envision where we use AI for anything remotely good sure would be nice, but with the way the world and the people pushing for this AI especially work there just isn't a chance in hell that's how it's gonna end up going.
