Taleb said Trump is not as "scary" as people make him out to be.
"In the end, Trump is a real estate salesman," Taleb said. "When you elect real estate salespeople to the presidency, they're going to try deliver something."
Because of that, Trump probably won't do anything apocalyptic, Taleb said.
The author further said he is against the two-party system and is voting for neither Trump nor Hillary Clinton. He said, however, that whoever wins won't make nearly as much of a difference as people think.
Taleb is best known for his 2007 book, "The Black Swan: The Impact of the Highly Improbable," in which he warned about the inability to predict unusual events that have severe consequences.
If Americans hand Trump the Oval Office, Taleb said, the reality TV star would probably tone down his bluster. But a victory for Trump would also mean a toppling of the bureaucratic elite, the author said. Trump's success in the primaries was due to his ability to harness popular support from the bottom, letting people essentially vote against bureaucrats, Taleb said.
He also said a Clinton presidency may not be disruptive domestically, but would be overseas. Taleb said Clinton is likely to be an interventionist internationally.
Taleb said Trump would be less likely to intervene in events overseas and would try to go with the prevailing winds among voters. Hypothetically speaking, if Trump felt that voters didn't care about events in a place like Egypt, Taleb said ,Trump wouldn't want to act against what voters want.
