Oof. I don’t have exact facts and evidence for my claims, but he does a pretty good job at giving his interpretation and summarizing various events while showing the sources he gets his info from.
Is there another tertiary source out there that wrote on this topic, not sure. Is his content 100% accurate, not sure either. But I can sure vouch for his videos being good and very well made. All the graphics in them remind me of studying for big finals, they’re easy to recall and keep you in the long ass explanation.
He has episodes on serial plagiarism in the scientific community, it would be very hypocritical of him to do the same.
