The answer to this is sponsorblock, which has reached a state where it takes mere minutes, sometimes seconds, for someone to mark the relevant segments in a new video. And it's not just sponsor reads, you can let it skip intros, unrelated tangents, etc.

The best feature of sponsorblock is the "skip to highlight" feature, which skips to the part of the video you actually want to see.
