When you say that after World War I there was a pandemic that killed more people than the war itself, most will say: "Wait, are you kidding? I know World War I, but there was no World War 1.5, was there?" But people were traveling around after the war, and that meant the force of infection was much higher. And the problem is that the rate of travel back then was dramatically less than what we have nowadays.

I remember in 1980 or 1981 looking at a list of people who had made a lot of money in the computer industry and thinking, Wow, that's amazing. But I never thought I'd be on that list. It's clear I was wrong. I'm on the list, at least temporarily.
