Nassim Taleb on Brexit

The European Union is doomed to fail, "Black Swan" author Nassim Nicholas Taleb said Thursday.

He told CNBC the EU has become a "metastatic and rather incompetent bureaucracy" that is too intrusive.

"The way they've been building it top down from Brussels is doomed to fail. This is 2016. They are still thinking 1950 economics," said Taleb, who is also the author of "Antifragile" and is an advisor to Universa Investments.
