Agreed. It's so annoying having good content buried in audio. For interviews of note on youtube, last week I cracked and spent 2 hours writing a yt-dl based ripper that converts the whole thing in to an html linkified webpage via intermedia VTT, opening the resulting subtitles based transcript file in the browser so you can easily scan and click anywhere you want to see the video and it will open in a new window at exactly that point. Not perfect but saves AGES.
