Its the celebrity effect. I even saw it with otherwise respected individuals like Neil DeGrasse Tyson. People fundamentally cannot understand that a person who is a subject matter expert in one are may be completely out of their element in another area. Add in social media letting then (intentionally or not) amplify their most mundane thoughts and boom. You’re ah “influencer” on any topic you choose to talk about.

Joe Rogan seemed different because he had the sense to bring other smart people on and let them talk. But that mask slipped off over the years.
