Most of the ones out there are weird, anti-configurable systems like mobile phone OS.
The only ones that really seem like "the future" in my eyes are Nix and Guix.
And I'm not going to use those because I already have a good setup with my conventional distro (Debian). Anything less than absolute perfection will not get me to switch.
Nix is imperfect because it uses systemd. Guix is imperfect because it has a smaller selection of packages, and a more difficult configuration system.
It used to be a whole weird wide world. Then the corpos got a hold of it, and now it's 5 giant spyware websites filled with screenshots of the other 4. Say what you will about the old web (NO HTTPS!) but at least it was human.
I used to have a synced framerate and AR capability, where I could project my thoughtscreen into the air, or onto a wall. I know what you may be asking, but no, other people could not see it.
Then I lost it over time, seems like one of the OS updates didn't support my hardware.
Maybe it's a leftover habit from the COVID pandemic?
