I didn't come off of this article feeling very impressed with Stanford's CS department. Someone with contextual knowledge please explain why I am wrong.

I've had my own calculus / discrete math / math for bio courses before but that was after several years as a doctoral student and TA at Georgia Tech. I can't imagine that there isn't a PhD candidate with more experience under their belt both teaching and using TensorFlow. The author even admits they volunteered to teach the course to stimulate learning the material themselves.
