But I am sure there is a majority of learners who prefer video/audio medium ( given the vast amount of video tutorials out there ) . If anyone reading this falls in that category, why do you prefer it? Genuinely interested.
Videos that effectively engage you visually are very powerful learning tools. For example, back when I was learning sorting algorithms, I was having trouble understanding merge-sort. I read about it in numerous texts, and I could implement it, but only because I had memorized the coding pattern. Then, I came across this video:

and in an instant it all made sense. Doing it well takes time, preparation, creativity, and often times a bit of resources. The youtube series Kurzgesagt – In a Nutshell does an excellent job of engaging you visually and I wish more online coding tutorials would adapt some of their techniques.
But, it's rare to find that so I when learning a new topic, I'll generally inhale a book or two on the topic.
If I'm watching a video tutorial from someone who understands the medium and is using it to its full advantage (including understanding editing and visualisation) that's a different story.
But - speaking as a former filmmaker - I know that doing something like that is neither quick nor cheap. It's "I wrote you a long letter because I didn't have time to write a short one" x1000.
Hopeless for reference, though, obviously.
