I’m amazed at how much production goes into each of his videos. His YouTube play button is well deserved.
As with blogs, a lot of this effort is wasted unless you get lucky. But with blogs, at least you have multiple good shots at visibility. Maybe you'll make it to the top of HN, maybe on X, maybe somewhere else. Even within a single platform, you usually have multiple tries. If you don't get noticed right away, there's still hope that someone else shares your content down the line.
In contrast, on YouTube, an algorithm essentially decides once. If you don't already have a zillion subscribers, it shows your video to a couple of people, more or less at random. If they don't engage, that's the end of the road.
