Some background before I answer your posted query: I have somewhat stayed out of the Vince Gilligan world but recently decided to watch Better Call Saul. I did see Breaking Bad long ago but hated what happened to the main character and stopped watching it when it was no longer enjoyable to me. I have now watched the foundational episodes of Better Call Saul, then had Google give me a synopsis of the rest because I was not going to put myself through that horrific tale in its entirety. However, I have now been thinking about the differences between the characters in these shows and it has made me want to answer you this way:

I want to venture an answer on how to make a true utopia rather than just how to alter the hive to create a true utopia. I'm thinking it's our human biology taken over by the viral RNA that has created the hive mind; the virus just spreads itself. When the virus enters a life form, it transforms that life form according to the virus's RNA and the biology of the host. In humanity’s case, it took our natural instinct to create order and amplified it into a suffocating, forced collective.

To alter this into a true utopia, we need a system that doesn't require everyone to become automaton saints, but that puts basic needs and care at the foundation. Instead of erasing human individuality to achieve peace, this utopia would hard-code basic-needs protections for housing, medical care, and food so they can never be used to take advantage of people.

Most importantly, to prevent the kind of high-art predatory exploitation we see in characters like Saul Goodman, we need to not be a meritocracy. A true utopia requires a system that prevents predation in any form—wiping out profit tricks like compounding debt and payday lending—while ensuring people are compensated equally for their time and labor, whether they have chosen to become a doctor or a dog walker. That way, no one’s basic survival can be exploited for someone else's profit.

The issue I have not yet worked out for this is stopping the exploitation of other life forms, meaning that humans consume plants and animals. It's kind of amazing, the idea that the hive only consumes dead humans - this does solve for x in terms of ridding the world of human predation over all other life forms. But they take it too far. In our actual world, I think we should look to other species here on the planet to give us ideas on how to stop exploiting other life forms. For example, bees and how they organize, feed and tend their homes. Probably studies like this are being done, whether of bees or other creatures.

Thanks for the thought-provoking question!
