What's the first thing you'd do with a Star Trek holodeck?

Two chicks at the same time.

Read the manual.

Have the computer render a fully accurate copy of myself, then circle my copy slowly, scrutinizing every flaw as they would be seen by others. This will surely be good for my mental health.

Ensure the safeties are enabled.

Disable safety protocols.

Depends entirely on whether or not it has an incognito mode.

Relive a random fun night with my college friends in a bar from 2003 that no longer exists.

Miss you, old friends.

i'd be getting my dick mad wet

I'll tell you what I'd do, man: two chicks at the same time, man.

Set it to humanity's highest point: 1999. Things will get very confusing when they try and break me from the Matrix only to find it we're in the holodeck.

So like ... how private is a holodeck? If the answer is "very", I'm definitely going with sexual fantasies.

Live my fantasy of being a star trek captain.

And during my star trek fantasy, I'd visit the holodeck.

Seven Seven of Nines

Assuming it will keep running indefinitely without maintenance or upkeep.

Go inside. Create a pseudo Renaissance era theme. (With modern medicine). Program it so my bank account in there won’t ever run out of money. Then never leave. Just keep exploring. Have the holo deck just keep reconfiguring itself to effectively allow me to explore large areas.

everyone know, its going to be PORN.

Get out as fast as I can, considering how often stuff goes terribly wrong on one of those...

Finding out where all the fluids would be going after ending the program?

I'd simulate being on the Enterprise with my space pals and doing fun stuff on the holodeck.

After all the porny sex stuff?

( ͡° ͜ʖ ͡°)

See if it will run Doom. Safety settings on, of course.

Then Bad Apple in full realism mode.

read the user manual

Lock the door from the inside

No, but seriously, are those things self cleaning or do you have to go all over the floor, walls, and ceiling after you're done with a black light and a mop..?

Your mom.

Is it weird I’d ask it to put me in a ST:TNG episode?

Girls. Sorry but its true. At least at first.

But then once that gets boring, I guess I would create beautiful environments to walk around in.

Remember when Bortus had the holodeck addiction?

Kinda like that.

Bang Margaret Thatcher.

I'm going to go fuck myself. 😃

Also: your username cracks me up 🤣

I can tell you what colour of uniform I wouldn't wear!

Riza simulation

Full Barklay

Well, it'll probably involve tentacles, I can tell you that much.

Bunny Island!!!

Insert funny porn joke.

But in all seriousness? A fully immersive, 100% realistic Dungeons and Dragons game with my friends. Exactly the same as we would run it at our table. We'd hop down to the replicators and holo-disguise generators and make ourselves up like our characters, and I'd just follow them around in a spooky mysterious robe and narrate the story.

That's it. I would run the best D&D game ever, the game of a lifetime, for my best friends.

Simulate a holodeck.

Then simulate myself simulating a holodeck inside that holodeck.

Then...

Can I use to learn the technology of the Star Trek era?
Steal all the patterns Invent unlimited energy, the safe teleportation not the crappy one from early ages, replicator technology, cancer cure, and medicine.

5 minutes with Seven of Nine

Fuck simulations of real-life environments, I’d run a fantasy RPG campaign.

Probably use the processing power for something else.

Honestly? The first thought that goes through my head is exactly how strong and responsive the force fields can get. IIRC they can do bullets, as well as the texture and movement of anything normal. So, probably some benchmark involving a bucket of paint I brought in. Start with the paint, then do weird things with the bucket.

Play DnD first-person

Create a Westworld-type environment.

Used or new?

Set myself up as Spider-Man. Its what I wanted to do since I was 7. Then some weird sex stuff.

Install Doom.

See if I can hook it into SteamVR and launch Resonite in there.

Might need some virtual controllers to do menu button stuff, but that should be easy.

There are a lot of good answers, probably some good simulators of things that already exist, programs people have made... I would test the ship's AI/learning capabilities, show it some old photos of my family and of memories past and see if it can recreate things like that. Since I don't have video of these people, I'd have to fine-tune their personalities and I'd have to remind myself I'd always be looking back — being that they aren't real people, I wouldn't be able to ask them about things they don't really know about or anything like that. It would be (more) interesting if we had input from a bunch of people who knew them, to sort of fill out the personality and try to remove biases.

But yeah, I think I'd start by showing it every photo I have of my childhood home and try to go back there, just to see it again.

And yeah, you can kinda/sorta do stuff like that now, there are programs... but that's my answer.
