The fundamental techniques of machine learning will always be there. For that reason, Ng's ML course will always be the prime entry point for people new to ML. As someone who has taken both the Ng course and has roughly watched the videos of the fast ai course and done some work, I would recommend first doing the Ng course. Things will be much more calm if you then approach the fast ai DL course. The fast ai course is amazing and hats off to Jeremy and Rachel for the great work. But without any idea of machine learning, I would say you will need to put at least 20 hours of work each week to work through it, and that is if you are also a really proficient programmer.
