If you lived in the star trek universe what would you change ?

Stop sending administrative officers on away missions. There are specialists for that.

This is a change I can support!
But flagship captains are still allowed to disregard the prime directive, right?

I'd be so gobsmacked to escape capitalism that I don't think my imagination could catch up with me. I imagine some of us would be back in the holodecks reimagining it due to Stockholm syndrome.

"Computer, load program 'Bear Stearns in 2008'"
Never watched the show. I wonder how they select who lives in on ocean front of California cost, who's on the second row and who's 30 miles from the coast?
- When travel can be instantaneous, location matters a lot less.

Incredible advancements in science! Blindness? Cured. Missing limb? Here is a mechanical one so good you can’t tell! And since there’s no currency in the Federation everyone can get everything they need.

Id get a full body check over for any and all issues and probably be some mad scientist somewhere playing with wild anti gravity forces.

Seatbelts for star ships!

And circuit breakers or fuses. Stop storing fireworks in the control panels.
- They had to make room for the triple redundant relays. Stupied star fleets specs!
Good call! And maybe we tie the boulders in the bridge ceiling to something, while we're at it.
I could almost go as far as not routing incredibly hot plasma through the helm officer's control panel, but I think I love tradition too much.
- No, you gotta have exploding consoles, that's Star Trek 101!

Would like never jack off

(Holodecks are affordable right?)

What do you mean affordable, the federation is post scarcity
They definitely cover that in Lower Decks: https://youtu.be/-YeTDrk5ayw

Holodecks as every home! Who needs furniture if you can live in a holodeck and summon furniture based on your needs or wants at any given moment? And why limit it to furniture? Furnishings and decor could also be holo'd! And beds, and windows, and could you Holo a Replicator to replicate any food you want? Feels like the possibilities are endless

I would have a deep meaningful conversation with two betazoids at the same time.

Ensuring that the Starfleet admiralty suffered... transporter accidents... and got replaced by somebody -- anybody -- with some kind of clue would be a good start.

Give everyone the ability to control their individual genome. Why should we still be “humans”? I want echolocation and night vision to start. I understand the implications of genetic manipulation and why it’s outlawed in the federation, but if EVERYONE can do it, I think it becomes a non-issue.

This comment right here, Section 31 officer.

Ruin it by making it into the Elite Dangerous universe.

Who cares about exploration and protecting emerging civilizations when you can make funny images with the galaxy route map and participate in huge system control wars for void opals lol.

Or give random items to Thargoids for a totally scientific process of investigation.

Stop all this Prime Directive nonsense.

There's no such thing as a culture's "natural progress" because there's no such thing as "fate". We live or die or change or stagnate based on random events and there's no saying that one specific course of events is the correct one.

Introduce the God Emperor of Mankind from 40k, sit back, and let the fun begin.

Starship consoles are now fully holographic. No more exploding consoles.
