The Importance of March 2020

The episode between Truman and Martin, I was just struck because it's a little similar to Trump and Powell. Trump was someone who wanted negative rates. He thought government bonds could be called like a hotel loan refinance at a lower rate. And then Martin wasn't was not an economist. Do you think that the person writing a book about the Fed in 10, 20 years will talk about March 2020 with the same importance as 2008 quantitative easing?
