That's the title of a TED talk given by Dame Stephanie Shirley. Billed as the most successful tech entrepreneur you never heard of, Dame Shirley started a software house in England in 1962. Her talk is educational, inspiring and humorous and well worth the 14 minutes you'll spend. A short Ideas piece, How Dame Stephanie Shirley Upended Tech World Sexism in the 1960s is worth the read and contains a video of a December 2013 TED talk by Megan Smith on women in tech history. Remarkable!
