Off the top of my mind right now:

- the kid from the AI movie

- the Sentient Intelligence from the Peter F Hamilton books

I think there are quite a few positive examples if you dig enough. It's just that (a) none of those examples are being used as the mold for what large tech companies are set to achieve, because (b) none of those examples imply the sort of capital or power-concentration incentive that a capitalist company would look for.

If it requires huge capital/power to bring the utopian story into reality and there is no capital/power incentive to do so, these stories will remain on paper.

Whereas, if the Torment Nexus story details how its inventors got to rule the world for a millenium, you can see how it's more interesting for a certain type of person to gather the resources to build it if they have/can acquire the relevant skillset.

That's a very interesting observation. Why do you suppose that is? Naively I suspect that humans can't envision that kind of utopia without some authority keeping it in order, and power is ultimately a corrupting force so the story always plays out the same.
