Find time to find a girlfriend.Now, I'm not claiming to be most sensitive Neanderthal in the cave, but I am the father of three daughters, and this raised my hackles. The small number of women in the audience didn't seem to notice or mind, but maybe they did, or maybe one would the next time he gave the talk. As a field, this is exactly the type of throwaway comment that we have to, repeat, have to avoid.
I mentioned it to the speaker afterward, and to his credit, he was not defensive, and said he'd remove it or change "girlfriend" to the gender-neutral "significant other". (I'd vote for removal. Why even go with the stereotype computer scientists can't find love?)
