Sometimes Veritasium does incredibly thoughtful work and explains a very interesting or ubiquitous topic, and sometimes he goes to Crane Naval Research Facility so that the u.s. Navy’s R&D guys can teach him about night vision goggles and he can do a little military propaganda. I’d say it’s about 50/50 whether a vid will be really cool or propaganda. There was a pretty recent math one that was a neat topic and also was used as a vehicle for a little anti China propaganda.
