My opinion is that Mark Cuban works hard, but he's opinionated most in the areas where he knows the least. He is not an authority on anything, except maybe sports team management. He got lucky selling a shell of company to Yahoo (a fool of a buyer) in the dotcom boom.... but his performance on shark tank and on his blog tell me that, he's confused his luck with talent.
Agreed. He's entertaining and probably smarter and more focused than 99% of people but his poor arguments make me think he's not a precise thinker and isn't mentally flexible. I wonder if he'd be able to answer this question: What would he have to be persuaded of to change his mind on this topic? (I wonder what everyone including myself would answer to this question.)
I wonder what his motivation is. Is he upset by poor performance in his personal account and wants to blame someone? Does he buy the shockingly confused media hype? Is he threatened by something he incompletely understands? Is he doing it to get even more attention? Is he trying to seem intelligent or gain even more status by jumping on a bandwagon to criticize a popular scapegoat?
