Is it really that bad? I’ve been reading some of the deep learning stuff and there are some pretty detailed ,lengthy explanations. One time I did notice that An author copied/pasted most of their content from an obscure blog (90%) and I was going to call them out but they did list the blog in their reference.

However I am still a beginner in programming as well as deep learning so maybe I lack the the ability to distinguish between real and fake experts.
