I now pay for premium, but many YouTubers have taken to do sponsorships. It's getting pretty egregious. There's a YouTube channel I won't name, where every video is a full 2+ minutes of sponsorship, paid content, please click like and subscribe, also we have Patreon, we sell merch. Even YouTube premium doesn't get rid of that.

Those can be manually skipped to some degree by jumping header or speeding up. I wonder if someone could write a browser extension to skip them automatically. I wonder if it could use AI or heuristics, or a crowdsourced database.

Your best bet for skipping this with machine learning would be to use a textual language model and the closed captions.
