The last video I watched of his was a debunking of flat earthers that was so bad it almost gave the flat earthers some credibility. Many of his 'debunkings' consisted of 'no, because science that's why' where the flat earthers had actually raised interesting questions where the answers provide a great jumping off point to explore things in more depth.

Taking ten years to come up with some simple experiments to debunk someone who is reasonably frequently publicly wrong and then labouring the point and being really condescending isn't a sign of someone being especially smart (although it's hardly stupidity either).

Its the typical build credibilty with debunking total nonsense and then use that to generate views on videos where he is suposidly depunking a lot more viable stuff.

Combine that with serving on the Anti-Musl wave and you have surefire way to be reddit famous.
