Most economists have no idea how monetary policy or macroeconomics works.
So why on earth would you advocate for the people who know the least about a topic to make the decisions? It's bananas.
There's no janitorial staff on Apple's board. There's no cooks on the Facebook board. There's no software engineers on the Twitter board. At least in industry we've - more or less - accepted that the folks with the relevant experience should be making the relevant decisions. This should be no less true in governance.
Yes there is. 3 out of the 11 members the board are clearly software engineers.
