When Elon Musk took over Twitter, two versions of reality emerged. In one, he was a free-speech crusader, a fearless visionary who could grab back power from Twitter's entitled workforce, motivate them to get "extremely hardcore," and multiply Twitter's profit and potential by orders of magnitude. In the other reality, there was the truth. Pulled from hundreds of hours of inside interviews with more than sixty employees, thousands of pages of internal documents, Slack messages, presentations, as well as court filings and congressional testimony, 'Extremely Hardcore' is the true story of how Musk reshaped the world's online public square into his own personal megaphone. Despite having workers with a decade and a half of experience confronting Twitter's most difficult problems - from massive engineering infrastructure challenges to tricky policy decisions that could sway elections - Musk decided there was only one voice that mattered: his own. You'll hear from those employees who witnessed the destruction of their workplace firsthand. There's the machine-learning savant who went all-in on Twitter 2.0 before getting betrayed by his new CEO, the father whose need for healthcare swept him into Musk's inner circle, the trust and safety expert who became the subject of a harassment campaign his former boss incited, and the many other employees who tried to save the company from their new boss's worst instincts, and paid the price. This is the story of Twitter, but it's also a chronicle of the post-pandemic labor movement, a war between reckless executives and a workforce newly awakened to their rights and needs. Juicy, character-driven, and filled with unbelievable revelations, 'Extremely Hardcore' is the definitive, fly-on-the-wall story of how Elon Musk lit $44 billion on fire and burned down Twitter. It's the next best thing to being there, and you won't have to sleep in the Twitter office to get the scoop"-- Provided by publisher
