I'd also include Regex in the list of dark arts incantations.

I'm ok with regex, but the ffmpeg manpage, it scares me...

I am perfectly at home with regexp, but ffmpeg, magick, and jq are still on the list to master.

Regex is only difficult because it's complicated, the primitives are all sensibly arranged and predictable. FFmpeg is layers of dark magic where the primitives are often inscrutable before you compose them.
