I'm jealous - all that time sitting around to get something productive done, and I can't concentrate at all because I can't relax, the plane suddenly shakes and distracts me, and it feels like I'm lacking oxygen and am not thinking clearly. I remember trying to code some stupid iterator thing in Rust for a few hours and couldn't crack it. On the ground it was solved in like 10 minutes.

Your phone has a "do not disturb" feature

I'm jealous of them being able to be productive _on a plane_.

I can be productive on the ground no problem, but I'm mostly useless when I'm on a plane.
