YouTube channel - senior software engineer

I'm thinking about creating some engineering content for different platforms, videos for YT, courses and e-books. While I understand the value of the last two, I was always wondering who would watch a 20 minute long video about setting up a specific technology with a specific programming language, instead of reading a 5 minute blogpost?

Here's an example: https://www.youtube.com/watch?v=1UcLoOD1lRM I watched it, it's a great video, but compared to a blog post in a YouTube video you can't:

• copy paste code. There might be a repo with the code that's being discussed in the video, but now you have two things to follow. You can copy&paste from a blog post while reading it.
• search for specific commands, words, filenames

What are the advantages of creating videos instead of writing blog posts in such topics?

Thank you for sharing your opinion!
