Casey is much better and more measured on this front than Jon Blow, who has a history of wandering into random comment threads on HN and pronouncing some topic a "solved problem" or "trivial", only to actually work on the problem himself a few months later and remark that it is more complex than he thought.

But because Casey and Jon are friends and frequent collaborators, and generally prioritize the same things, they get interpreted as sharing each other's views about everything. They don't, but the mischaracterization is not easily dispelled.
