Alternatively: you can listen to audio while commuting or driving or cleaning or working out. I love audio for higher level things and to get an overview of the topic. Then text to dive into the details.
Another big driver to move from text to video: It is easier to monetise video via YouTube compared to a blog. People with millions of subscriptions on YouTube aren't creating FE learning material out of the goodness of their hearts; it is a big business. Also, video is almost always lower information density compared to text, so it is easier for your net to capture more customers.
And you can't just search in it. It's truly trashy format for anything other that presentation or lecture. For simple information sharing it's horrible.
