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.
Disengage the safety protocols and suddenly you’ve got weapons and shield emitters than ought to work just as well as their material counterparts, but can’t be damaged (or any damage can be instantly reset). We know that holograms can be projected into space so the only limitation would be the range of the holoemitters.
Hey now if we’re using the practical applications of the tech then the warp field emitters could be used to simply tear ships in half with as much or less energy than it takes to move the ship in the first place, or cause planetary cores to collapse into micro black holes, or create an inverted artifical event horizon around the ship making it physically impossible for weapons fire to pass through it because the direction of ‘through’ simply no longer exists.
