Just as the comment up there says that HN comments that are critical and misinformed get a lot of attention and upvotes, Prasad has been highly critical and misinformed about scientific research, and his stint at the FDA has exposed that his critiques are much like that top-level HN comment that doesn't get things quite right.

> not the type that would usually violate tenure
