The extension 'sponsorblock' automatically jumps over ad reads in the video, with user-submitted start/end data.

I’m always surprised when I watch a video that is 9 minutes old and the sponsors segments get skipped automatically. That extension must be getting quite popular.

Can't recommend it enough. And with this plugin you'll immediately notice if a video is vapid (read: only exists to plug the sponsor.)

How does the extension know if the submissions are valid and not malicious?
