Ask HN: Your favorite TED Talks to help me prep for mine

Hi everyone! I've been selected to give a TEDx talk about the gender gap in technology and about how I, while working with a nonprofit, am working on closing this gender gap. Please help me by: 1. Sharing your favorite TED talks 2. Sharing your least favorite TED talks, or ones that weren't done in the best way. 3. Sharing any research/resources you might have for information about the tech gender gap, or any books you might recommend I read!
