It’s not that books are better than YouTube, in many cases (like visualizing math) books are much worse than video, but for a lot of topics books are the only source that goes in depth on a topic. It won’t necessarily be the case a hundred years from now, but right now if you want to study a topic that had been around for more than 30 years you’ll probably have to invest time in books. And the part that isn’t mentioned here is that most of those books are out of print so you will need to dig through libraries and maybe even use the Inter-library loan system.
