People. We can all disagree with Mr. Thiel and call him a scumbag which will make him more extreme and everyone off more poorly, or we try to understand each other in the hope of getting to a better place.
I disagree with many of Thiel‘s viewpoints, but also agree with many of his viewpoints. For example, he beliefs that the government should be smaller and I think that there is certainly a point there. As Taleb also has argued, it’s better to have systems as small as possible so governments should probably be smaller. Look at the effectiveness of small countries like Switzerland for example. Or look at how ineffective academia is.
