It just popped up in my mind.
- You could decorate any room as you like. You don’t even need to step out of it most of the times.
- Other people can be projected inside it like Voyager’s doctor.
- Also rooms could be much smaller. They only need to be big enough a human(oid) can fit inside.
- In emergency cases most holograms can be shut off to match increased energy demands by weapons and shields. You only really need seating/bed and a (non-exploding) console screen.
- Much of the specialized rooms like a bar, med bay, etc. won’t be needed anymore as a holodeck can imitate all of them.
It irritated me a bit that a Discovery gets fancy floating warp nacelles but holodecks are… wait, does Discovery has a holodeck? I don’t remember seeing one.
I mean, the largest holodeck ship I can think of was the one from Insurrection, and that was specifically designed to secretly abduct a whole population without their knowledge. I don’t think it would work for exploration or combat, just transport. I think they started incorporating holoemiters into systems on all decks by the time of the Enterprise-E, but they were supposed to be supplemental systems, not replacements.
I just don’t see how these holoquarters would improve much. Like, what real-world things are you replacing? You’ve already said that they need to have real-world seating and beds (and I’m going to go ahead and add bathrooms to that list), so what are we phasing out? Clothes and personal effects? Sure, you can replicate a new uniform every day, but it’s probably a waste of energy, and you wouldn’t have space for sentimental possessions.
Being able to go on some sort if multi-player adventure sounds cool, but I think most people would prefer to able go out to a real bar with their friends rather than go to a virtual bar from their bedroom. This is starting to feel like how Zuckerberg tried to replace meeting rooms with VR meetings. I think most people would rather go to a place and see someone real face-to-face.
And holodoctor or a holographic patient interface is even more risky. Even if you assume that a holodoctor is just as good as a real doctor (and there’s really only been one EMH that was), or that a holographic version of your patient is exactly like the real thing, all of the problems with holographic medicine I mentioned get even worse. Imagine being halfway through surgery when your doctor just dematerializes.
