Magnificent! Add several gifted (but undeclared) brooches and this is truly an outfit to be worn 5 days a week!
She just doesn't pay any attention during editing whatsoever.
She's said a few times before that she sees the editing of writing as "boring" and "mindless". For most people it's a core part of the writing process and a crucial opportunity to grow and improve, but for Ruby, the idea that she didn't nail something perfectly on the first try and has to entertain the notion that she made a mistake and has to improve at something is completely insulting to her. She sees it as an unnecessary, time-consuming obstacle to her innate (imaginary) genius.
She seems to look at editing a video the same way - she does the bare minimum to make sure a video is a certain length and features all the sponsors she needs to show, and that's it. No second takes, no reviewing the audio, no double-checking the footage. Just slap together random footage and call it a day, no matter how much incompetence, technical glitches, continuity errors and self-doxxing stupidity she left in.
Not only are all her videos full of problems because she wasn't paying attention at any point, she's once again robbed herself of the opportunity to improve at something over time - spotting regular errors and learning not to do them next time, and so on. Anyone with 7 years of experience filming and editing should be a pro by now, but she's no better than the day she started.
