I don't think any utopia is reachable, but closest to that would look like Star Wars EU computing, where proprietary formats and stuff like what we use today are limited to toys for very rich people, computer systems are produced by a lot of different processes in a lot of different places, even if not very computationally powerful, everything is modular and tunable, and vendor locks are too a thing only for expensive toys.
Formats and environments and interfaces are simple, because of the need for portability of everything in such an environment. It's not impossible there to successfully integrate systems produced 100 years apart.
EDIT: What I meant is - it definitely won't happen the way we are trying now with centralized very complex and fragile systems built after what normies imagine to be good. Normies want magic - all-powerful arcanely complex systems, a deus ex machina. This is the direction exactly opposite from what a good engineer wants. It's scary actually how a lot of things around are attempts to replace the "wrong" humans. "Wrong" romantic partners, "wrong" employees, whole "wrong" professions (like many lawyers seem to hate engineers, and the other way around TBH), politicians try to replace "wrong" social responses with bot farms. Everybody is trying to use computers most of all to kill somebody else indirectly (or sometimes directly). I wonder when will it get to general conscience that this is not different from any other technological advancement.
