He is smart, but smartness is overrated.

How do I know? Because I am pretty smart as well, with a PhD from math, but that didn't stop me from making a series of stupid mistakes in my life. Sometimes out of sheer optimism, sometimes because I missed some crucial information, sometimes because closeness to some other person made me miss important red flags, sometimes because I overextended my abilities, sometimes because I underestimated my adversaries.

If I bought Twitter, I would have run it into the ground in days.
