I'm trying to imagine all the useful things you could do with code generated videos.
I'm imagining a daily routine of airplaying the video to your TV with an annotated dashboard of quantified self metrics, weather forecast, plotted local Covid-19 cases, health advisories, etc.
I don't know about that. If I'm making breakfast and can see a screen, both narration and visuals are useful. I think that's why Google and Amazon came out with device assistants that have screens
If you are making breakfast and have a system that rotates dashboards (such as Grafana for example), that is exactly the same as having a video from the viewing angle, but otherwise better, since you can still come from the room and do some interactive stuff not possible if it were only on video.
So, video is only limiting you, nothing else.
I can imagine this to be used alike to PDF in specific contexts - if you need 100% guarantiee that local devices/viewers/etc wont change any output detail.
