The first modern pandemic – This is a long post (20 min read) by Gates talking about COVID-19 pandemic, it has a great introduction talking about growth, the difference between countries, and people’s behavior. But the focus of the post is the innovation needed to beat pandemic, it separates the innovation needed into five categories, treatments, vaccines, testing, contact tracing, and policies for opening up. If you want to read something non-tech I pretty recommend it. This post has a short version too if you want something short.
