I got into bed and realized from the glow that I had forgotten to put my PC to sleep in the next room.
Instead of getting back out of bed I opened the steam link app on my phone, and pressed the main menu button to get it to turn off the system.
Being able to do Jetsons shit like this sometimes makes me feel a little bit better about tech and the present. Just a bit though.
(Similar feeling: sitting in the cafeteria at my office job back in 2018 or so and realizing that for some reason I can see my own Plex server from the phone app and then being able to remote-stream the anime I had downloaded into the library on my lunch break)
