We are better off leaving the appeal to alternate time lines for another conversation, preferably around science fiction or comics.

As it exists, as it was created, "AI" is evil. It consumes resources we can't afford to waste and is currently supercharging our pollution indexes and creating what may be a catastrophic collapse of already very fragile and unbalanced social and economic realities.

And because we are already into the sunken cost falacy fase, it will never be rewritten or rebuilt. Hopefully, it will collapse in such horrifying way it will create a cautionary tale, but we are not so lucky, so what we are left with is picking up the bits after it.

This kind of system had to be developed inside laboratories, colleges, universities, research centers, to aid into very niche and specific fields of research, not made to be a mass consumption comodity as it is. But it was, as you very well put it, not done that way.
