I remember this question actually being an assignment in an early college sociology class. I couldn't manage to answer it in the way the instructor wanted, because I don't believe a true utopia is possible.
Humans thrive on challenge, and utopia removes challenge. Utopia implies no struggle, and struggle (so far) is an integral part of the human psyche.
But if a utopia could exist, there would be lots of cats. And penguins.
Automated production of basic necessities advancing to outpace the needs of mankind as we halt the growth of our numbers. Luxury itens being generalized as we became able to perfectly emulate reality in simulation, thus making everyone live like kings something very cheap.
I see how many would argue this to be dystopia and not utopia, but I'm not a real world snob
You've just described
Earth in Star Trek: The Next Generation. Nobody wants for anything, other than compassion, as Picard basically rolled his eyes in the episode "The Neutral Zone" and said 'why did you bother' when his crew revived three 20th-century people they found in cryogenic freeze. Picard and Riker made sanctimonious speeches about how
superior 24th-century people were because all poverty, hunger, etc. had been eliminated, after chastising Beverly for reviving people who were "already dead", curing them of the diseases that had killed them, thus saddling Picard with the inconvenience of having them on board the ship until they could send them back to Earth. That was the episode in which I realized that while I like Patrick Stewart as an actor, I loathe Jean-Luc Picard for his reprehensible arrogance.
Well, elimination of poverty and hunger and even greed may be true on Earth, and in Starfleet. It wasn't true for Tasha Yar as she starved and struggled on her home colony where the government and society had broken down, or for the colonists and Maquis in DS9. As Sisko put it in an episode of the latter series, "It's easy to be a saint in Paradise".
And as someone who grew up with people who were artistic (my grandmother was an artist with paint and with sewing, knitting, and crochet; my dad was an artist with woodworking, leatherwork, and drawing; I'm a needlepoint artist, working in 2-D and 3-D needlepoint and I've composed music)... I've learned that there are some things a machine just can't do.
A virtual lucid dream is a sure fire way to remove all conflict
