The most influential people during COVID-19
While working on research for my book about my work during COVID-19, I wanted to include those who also fought for science, transparency, and the public’s right to access honest and accurate information and data.
So I cheated. I asked AI to generate a list of the most influential experts during COVID-19 with a brief description of their notoriety during the pandemic.
I’m familiar with all of these people, though I will note that many of the people included were certainly “influential,” they did not have a net positive impact on public health.
I’m putting this out there to see if you have any suggestions for your own heroes during COVID that I should include. Not everyone has to be a public official or director of a major health office. Local leaders often stepped up and defied the tides of disinformation in protecting people. Private organizations, community groups, and faith groups also led the charge in making up for the inadequacies of our state and federal systems.
After reviewing the list, please add your own recommendations in the comments below, and share this piece so that others might contribute. I’m nearing the end of the research phase of my book and want to, at a minimum, recognize those who helped keep the world from falling apart in any way they could.
