Why are you in such a rush? Relax and enjoy the experience. Would you go to an opera or play and then ask them to rattle through it as quickly as possible so you can get out again?
It's one of the reasons I prefer books to audiobooks - I can slow down and enjoy the speech/intricate descriptions, but virtually skip over 'functional' words.
I'm not sure why this is done - whether it is to make the video easier to follow for non-native speakers, or to give a more 'authoritative' feel (slower speech = more confidence etc?), but I find such videos unbearable to watch at x1 speed.
So for me it's not about rushing and not enjoying the experience. It's about listening to it at a speed which is bearable: and hence enjoyable.
It's to stretch the videos that are just under 10 minutes to longer than 10 minutes so they can add mid-roll ads.
Whenever you're wondering why the video is too long, or why the author is somewhat rambling around the point, or why they include those "like and subscribe" sections in every video (sometimes at the beginning, because you'd close the tab otherwise), the answer is always to find that sweet spot that accommodates the ads. It's also why channels tend to upload videos of similar length, regardless of the topic. Sometimes they have to cut the script short, other times they have to find a way to lengthen it.
Warren Huart does this end of the video, and I now really appreciate it when he and others do it. I mostly watch YouTube on my Samsung TV, and it takes forever to navigate through the YouTube app's onscreen menus with my remote control to find the Like button. If they don't talk for long enough at that point, I get kicked out of the menu and dumped into an ad & another autoplay before I get time to click their like button.
If the YouTube algorithm has any sense (probably not), a Like after someone has just watched the entirety of a 20 minute video at normal speed should have more weight than someone who clicks Like in the first 2 seconds of clicking play.
If we use walking as an analogy, sometimes people really do need to slow down and smell the roses, but certain speeds of walking for certain body types/fitness levels are just genuinely awkward/painful...
