what’s the longest you went without sleep?
My answer is almost exactly the same as yours. It was me and my friend doing it together.
Do most people still use computers, or do people only use a smartphone as their main/only device?
I'm on my laptop all the time, and I don't use a smartphone at all. I'm not a luddite, I just don't like the world of smartphones. I enjoy being disconnected when I'm out. I enjoy using an OS that I can control and modify to my heart's content. Am I weird? Do I care? My friends keep forgetting and try to send texts to my landline though, which is annoying. I might replace my landline with a dumb phone, maybe. Ftr, I'm a millenial.
What's your favorite DE, and what does your workflow look like?
Cinnamon. I feel like it's a nice middle ground between the minimalism of Gnome and the maximalism of KDE Plasma
