SAN LEANDRO, Calif. — There have long been complaints about the lack of women in the tech industry. Now there’s a towering female figure, in a tech park across the bay from San Francisco, although not quite what some people had in mind. A 55-foot tall statue of a nude woman unveiled this week in the working-class community of San Leandro is stirring controversy and a lot of conversation. At the base of the 13,000-pound statue is a message in 10 languages that says: “What would the world be like if women were safe?” The statue — roughly three times as tall as Michelangelo’s David — is made of steel mesh in the form of a graceful dancer, with an arched back and arms stretched overhead.
