You are basically making a claim that he is a bad businessman without mentioning that he is one of the richest people in the world. Why should anyone take your arguments seriously?
He signed a binding acquisition agreement in a $44 billion dollar deal without doing any due diligence. Bigger deals have been struck on similar timeframes, but rarely has the purchaser evidenced such obvious buyer’s remorse so quickly afterward, or embarked on the venture with as little thought as he put toward it.
That’s a pretty weighty fact on the scale of “Musk - canny businessperson, or remarkable streak of being in the right place at the right time.”
So you suggest he is a bad businessman and his success is only attributable to luck. To understand how ridiculous this claim is you first need to realize that there are infinite ways to fail and very very little ways to succeed. Good and bad decisions are not symmetric, it is not 50:50, it is more like infinite:1. But even if it was 50:50, for the thought experiment sake, if you make random decisions you quickly make a bad one, and to be successful you need to make way, way more good decisions than bad ones. Sure luck is obviously always a factor, but thinking that he created a car that he later sent to space on his own rocket is not a sign of extraordinary competence, well, to me you can as well claim that the Earth is flat.
