Linux

Shucks, I switched from screen to tmux over a decade ago, simply because (a) screen wasn't a ubiquitous tool, and (b) tmux was superior in almost every way. I haven't encountered screen in the wild in years.

a) is still important; I like and use ripgrep and fd, but grep and find are still useful because they're always installed, everywhere that's even halfway POSIX. ripgrep and fd aren't everywhere - e.g. BusyBox. But screen isn't in that core toolset, so there was little reason to hang on to it.
