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.
Probably the walls. Without them, the ceiling would collapse and everything in the room would be useless.
Me!
The clock on my PVR (01:59) and the light switch. It’s time for bed…
My glasses, my eyes are completely fucked so I really can’t do anything without them.
Nah there are studies that show that if you go blind suddenly you will start to learn decent echolocation within a few hours, meaning in a room they’ve never been in they can use a clicker and not walk into things. You can already do it you just haven’t ever done it consciously. It’s your phone.
Myself. Which I see as a sign that I need better stuff. I am a low bar.
Would “my phone” or “my computer” be too cheap as answers?
My phone. A Pixel 6a with GrapheneOS.
I actually use my tablet with a logitech keyboard and trackball more but the phone can do things the tablet can’t.
My cat’s not very useful, but he’s heckin’ cute.
Winner!
Me
The tap, it generates water out of the void
The bidet.
This guys bidet.
Oops. Tied for first!
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.
Also now I’m in the bus, so the driver.
I’m cleaning my basement, so I’m surrounded by tools, warm winter clothes and blankets, and bicycles.
But probably the smartphone in my hand.
