Does the author really know if Musk is "overloaded?" Of course not. There is no way to know this. The author can infer and conclude based on their own experience juggling projects, however assumptions made in a vacuum are rarely accurate. Juggling is almost always a function of effective time management, which successful people are known to be quite good at.
