YouTube is testing a mystery button that starts playing random videos

This is a most excellent place for technology news and articles.
I don't mind videos that are exactly as long as they need to be, they can be 1 minute or 1 hour or whatever. But personally I don't need skinny portrait mode and no seeking.
Everyone's different. I've watched videos on shorts that I would never click to watch and I really enjoyed them.
Seeking is avaliable on the mobile app. You can also do this trick on desktop Firefox where you click the picture-in-picture button and press back or forward to jump 5 seconds.
