Course Mash

EdX Udacity MIT and the list goes on and on for ever. These infinite courses came into existence on the internet in only 22 years. Before that just about 30 websites existed in total(as per a documentary on YouTube). Now that's awesomeness!
But it also confuses me - which among them is good enough. I found the EdX website a few days back - The courses there come from different institutes and foundations. Again they have about 500+ courses in total and scrolling through all that in their mobile app took me almost an hour. The life of the next genius would be much easier than Einstein, won't it? We have all the resources at our disposal and now its upto us to form and invent our own theories from them.
