TED talks are usually good, but there are exceptions. Rosin may have been intentionally obnoxious in the talk so men realize their macho non-sense. She does not have to be a bitch to do so. Many other speakers are conveying their excellence without refereeing to their gender and many of them are truly remarkable. This seems to be the majority opinions posted there. She was rated as obnoxious and unconvincing which are rarely seen in TED.

Obnoxious Unconvincing Informative
Just think about it: if a head of national laboratory related physical science came to give a talk and showed data after data on cheery-picked topics demonstrating men were more competent very arrogantly. Is that convincing?
