Honestly the constant jump cut style of editing feels so unnatural to me... I'd rather watch someone takes pauses and not be taken out of the moment.... I'm sure this has applications particularly in advertising/marketing but it's not without outs issues.
Most people can read 5-10x faster than they can speak. Videos are very difficult to skim compared to text. If your video is trying to inform people, and there is no emotional content that's lost by cutting, then you're playing a losing game time-wise against just publishing text. People get bored pretty quickly, so people use jump cutting on YouTube to increase information bandwidth from the default that's frankly unacceptably slow to many viewers. None of it actually ends up fast enough for me, it is rare that I will suffer through a YouTube video that I could read about instead. In order to beat reading, IMO you need to use the visual bandwidth too, like 3Blue1Brown does. A talking head YouTube video is the worst of all worlds, but that's where people's audiences are, so they're just trying to make it bearable.
Cutting also removes ums and ahs. Newsreaders take ages to get good at this at speed, so giving people these tools makes video more accessible as a publishing medium.
