I wish paid programming content was on average better. My assumption for paid content (outside of a university course) is that it will be awful. Paid programming content has consistently fell short of my expectations. Coursera is much better than average here imo, with courses like Functional Programming in Scala by Odersky and Andrew Ng's AI course. Pluralsight, Udemy, Udacity, all of them I have found to really be lacking.
