Bad take for two reasons:

1. Being consistently funny requires intellect and general cleverness. You can't be quick witted if you're stupid.

2. More importantly we are all mostly ignorant. You could have a PhD in 3 topics and have spent years in higher education, and you still know only a tiny speck of all that there is to know.

I'm not a fan of Jimmy Carr, especially after the Saudi shit, and I fucking hate AI. But the idea that we shouldn't value the opinions of artists is pretty dumb. There are plenty of smart artists with interesting things to say and unique perspectives.
