Bill Gates recalls once being invited to speak in Saudi Arabia and finding himself facing a segregated audience. Four-fifths of the listeners were men, on the left. The remaining one-fifth were women, all covered in black cloaks and veils, on the right. A partition separated the two groups. Toward the end, in the question-and-answer session, a member of the audience noted that Saudi Arabia aimed to be one of the Top 10 countries in the world in technology by 2010 and asked if that was realistic. "Well, if you're not fully utilizing half the talent in the country," Gates said, "you're not going to get too close to the Top 10." The small group on the right erupted in wild cheering.
