She didn't know one iota.
A couple of days ago I posted “Modern” C++ Ruminations and I’ve gotten a lot of flack for this comment:
Not knowing the history of iota() should not be something to be proud of, but an embarrassment.
I posted a follow up thread on Twitter to clarify the comment but the article, and criticism has spread to reddit, Slack, Disqus comments, and emails. So I’m writing an expanded followup here.
