Reading about #mansplaining, I am reminded of that one time I was introduced to a tech transfer manager as a tenured member of a machine learning team. The guy then proceeded to explain machine learning to me. This was at a lunch, and half the people at the table stopped eating with their mouth half open.

And now I remember another one.

I was giving an intro to machine learning to an audience of biomedical researchers. One man had the following question: "I am wondering why you're calling it machine *learning*, when it obviously ought to be machine *teaching*. Maybe you've been confused translating from the French 'apprendre', as it can have both meanings? Have you checked the translation?" Yes, it had been said when I was introduced that I did my PhD in the US and that I was a machine learning expert. And then I shared that story on Twitter, and a man who was *not* a fluent French speaker told me that my story was probably wrong, because "apprendre" only means "to learn" and never "to teach".
