Standing on the bus stop, so, uh the road? But that wouldn't be useful without the buildings and all the activities in them that bring people here. Or since the room could be considered the general "outdoors", oxygen, or stuff like that.
The chances of the most useful thing in the room being my phone is pretty high no matter what room I am in, since my phone is usually in my pocket and also modern phones are one of the most useful tools in existence.
Depends on purpose. We’re complex creatures. Sometimes we need food. Sometimes we need to stay warm. sometimes we need to battle the dark thoughts in our head.
Arguably. Though I could just use a hole in the ground. I'd say the sink is a close second. If I was in the wilderness and I needed to choose one though, I'd choose the toilet paper.
I'm out in a gazebo with nothing around me, so probably the sleeveless argyle sweater which is doing a better job keeping me warm than my blouse/skirt.
My computer. It was the most expensive one in the store when I bought it, and besides a not so great wi-fi adapter and ageing HDD's, this computer's been amazing for gaming sessions! The only physical console I've touched in years has been the Nintendo Switch due to the exclusives.
I'm rocking in a hammock in my backyard, while the portal solar panel I got for camping charges my bike battery. The sun is definitely the most useful thing right now, giving me next week's commute!
Want to sit? The chairs. Want to see? The lights. Want to not fall under the building? The floor. Want to get out? The door. Want to swim? The pool. Want to get out of the pool? The ladder. Want to get changed? The changing room. Want to warm the room? The heater.
Uhhhh. Probably the fridge. Maybe the microwave/oven combi, but the microwave no longer works so it's a bit less useful. If you purely look at the basics of survival then those would probably do it. Maybe the heaters, because surviving in a cold room is also pretty shit.
You could also argue that the smartphone I'm typing this on or the laptop are the most useful. It really comes down to semantics of "useful".
My iPad. I can not only doom scroll Lemmy, but keep up on news, read, play music or video, consume all the worlds knowledge. Also I can order food or anything really
