Here's a tip that works on YouTube and almost any other web page that shows you a video. You can increase the playback rate beyond the usually-exposed 2x by running this in your browser DevTools console:

document.querySelector('video').playbackRate = 2.5

I find this is the fastest I can reasonably watch most videos at, with subtitles on to help my comprehension - it turns a 40 minute video into just 16 minutes, short enough that I don't feel too guilty taking time off whatever else I'm doing to watch it!
