Billionaire tech mogul Elon Musk has denounced a new book claiming that Silicon Valley “tech bros” engage in sex parties, orgies and drug use in a long-winded rebuke to failing to get dates in high school.

Emily Chang’s Brotopia: Breaking Up the Boys’ Club of Silicon Valley, published in February, claims that “household name” tech titans, including individuals involved with tech giants such as Google and Uber, regularly indulge in group sex after being invited to what is ostensibly a regular party but which rapidly turns into an orgy as the night goes on.

Chang described one party in particular, confirmed by WIRED Magazine as being hosted by venture capitalist Steve Jurvetson, cofounder of the firm DFJ, that she claimed climaxed in what is referred to in the industry as a “cuddle puddle” – a euphemism for group sex.

But Musk, who was identified in an essay for Medium as someone who attended the party, has now said that while he was there, the party wasn’t in fact anything of a sexual nature.

“Emily Chang’s article was salacious nonsense,” Musk told WIRED, referring to an extract of Chang’s book that was published in Vanity Fair. “She conflated what happens in [San Francisco] sex clubs in the Tenderloin, which have been around long before Silicon Valley was anything, with boring [Vice Chairman] parties on the Peninsula. That is misleading to the public and she should be ashamed.
