Sweet Tweet Treats

For mysterious reasons, this old tweet has attracted almost 200k impressions in the last day or so:

I'm always amazed that so many people have strong opinions on topics like Nature vs Nurture, How the World Works, How Civilization Advances (or does not), without having examined the evidence.
