Of course if you read every available online course, buy books, you can teach yourself CS. I'm always more interested in reading quality material, that teaches things quickly and efficiently, with practice and not just long theory, without going into dark details. Those material are more rare. It's also often more interesting to learn about subjects you're interested into, instead of just "learning CS". I have an allergy to academic materials, and reading books that teach theory without explaining their application. Math is important, but it's a mean to an end, and to me it's better to teach CS with code. You cannot teach the proper math to everybody. The finality of computers is to use them by writing code and algorithms that perform well or better. Analyzing computability and other theory seems like applied math, so it's not really applied to computers science in my mind. Being able to pick up machine learning is great, but there won't be many individuals using that sweet math to do CS research. I used to believe programming was always a field of research in a way. It's not. You don't see random developers building ground breaking algorithms that change the world. That doesn't happen. Programming is about engineering and tinkering. You don't need to teach yourself computer science, you need to teach yourself more math, or learn programming, or learn electronics.
