I was a big fan of HI and Grey, until I started to notice that a lot of the stuff Grey talked about was a bit misleading or straight up wrong. Theres now quite a bit of “CGP Grey debunked” style videos by people who actually know their stuff, based on what those are saying, I have no interest in watching any more Grey content.
Oof, I always wondered if there were more things of his that were inaccurate.
What I caught was the hexagon video and his claim about triangles (combined to make hexagon) being the best for building rockets. I worked in the launch side of aerospace at the time, and true Atlas V and Delta IV were built with triangles… But only on their booster tanks. Their upper stages had a completely different design structure, as do Vulcan, Falcon 9, Starship, New Glenn, Electron, etc etc
Triangles were only used on Atlas V and Delta IV because CAD in the 90s didn’t do rectangles very well. That’s not a problem anymore, so triangles don’t get used
Sadly quite often these youtubers and others who speak a lot about a lot of different topics with a sort of surface level understanding are very often quite badly wrong. Especially the ones who say stuff like “X is best because its used in Y application”
That level of simplification is not very healthy for most stuff. Of course, there are some channels that do talk about a lot of topics but do very good research and/or ask for experts to help out with their script.
