Is Learning Artificial Intelligence via MOOCs a waste of time?

I remember having written a response that was specifically focused on Andrew Ng's Deep Learning training that was launched with a lot of fanfare in October last year. I have added excepts from my Quora answer here and there and this is me just visiting my own answers based on my year long experience since June 2017 working with CEOs and Chair(wo)men of large enterprises, training about 9000 people in my classical (meaning hands-on workshops where we learn the old fashioned way face-to-face) and interacting with tens of thousands of learners worldwide. I will however be brutally honest about my initial observation of the first 1.5 weeks -- which I went through yesterday with great anticipation and truly enjoyed (still enjoying!), of what I experienced. This may actually not have anything to do with his capabilities or intentions rather it("the dilemma") owes this to latest trend (pretty much close to madness) of packing a deep learning course in a MOOC and try to teach to folks everything in bunch of nutshells. I'll get to that in a minute, but first my quick analysis of who this Deep Learning course / specialization may or may not be for. So, who might this course be for?
