It's also arguably not a good set of tutorial unless you want to know how to solve puzzles. Shader programming for games or most purposes do not use the techniques taught in those articles. Those articles are all about what happens on shadertoy. not what happens in something like UE5, Unity, Tensorflow, Google Maps, Photoshop, etc...
I don't know a good place to recommend to use more common techniques. A few though would be
Of course if you enjoy the kinds of techniques Book of Shaders teaches then knock yourself out. I've written a few hundred "puzzle shaders". I just know I'm solving a puzzle which can be super fun and I might learn stuff that's relevant elsewhere but at least I'm fully aware that most of what I'm doing is not really related to how GPUs in the majority of situations.
