As a woman writing on science and technology, I’m used to being in the minority—but this was pretty extreme. Looking around when I first walked in, I was surrounded by men. In the packed room, which must have accommodated hundreds of people, the number of women was in the single figures. One was behind a camera filming the event, and several were quite obviously accompanying male partners. On my own, with blonde hair, red lipstick, and a faux fur coat, I stuck out like a Trekkie at a Star Wars convention.
