Personally I don't want shorts on YouTube.

I use and like you tube for longer content. If I wanted short content I would create an account with instatok and tikagram or whatever the next thing will be called.

Every week or so I have to go through and click not interested on all shorts suggestions.

I second they need an option to hide. I've sent feedback to YouTube numerous times and I know others have, but my guess is it will fall on deaf ears as they try to keep up with the current cool kid.
