David Sacks wants to run for President. He watched Trump's election closely. He wants to be the smart guy that uses the idiot's playbook. He is working hard to get placed on as much media as possible as a commentator. He is connected to many of the richest and most powerful people in the country.

He is, at the end of the day, a bored billionaire with some very pedestrian ideas. He does go to great effort to shout them louder. He does seem to have some serious ego issues, but I guess what politician doesn't?

I think the hilarity of Calacanis literally tweeting his own similar ideas is that it was a transparent attempt to be louder. ie: he just didn't feel heard about his ideas, so they needed amplification.
