No idea who this smart alec is. In fact I am not sure I like him, he sounds like he will be insufferable at dinner parties for the next 20 years or so (“you know, I predicted the Great Unwind of 2008-2010”). But this video indicates 2 things to me:
1) stating very definite opinions about outcomes which will be determined by the market is not always good. State assumptions. Hedge. No matter how convinced you may that you are right, there’s at least a very small chance you may be completely wrong
2) because of this, even if you vehemently disagree with someone you are sitting next to in public, especially on TV, it is always good to be polite. Do not engage in exaggerated passive-aggressive sighing and gasping.
Spinoza was always scrupulously polite.
