Read by Elon Musk, Richard Branson, Stephen Hawking and 2 others

Elon Musk taught himself rocketry from books before founding SpaceX, and the reading he has flagged over the years, gathered here as 34 book recommendations, reflects that self-directed engineer's mind. The trail runs mostly through his posts on X, formerly Twitter, and interviews ranging from the Rolling Stone profile to the MIT AeroAstro symposium. The books cluster around philosophy, society and politics, science and technology, history, and science fiction. His most-cited touchstone is Douglas Adams's The Hitchhiker's Guide to the Galaxy, which Musk describes as "really sort of an existential philosophy book disguised as humor." That sits beside hard-engineering primers like J.E. Gordon's Structures: Or Why Things Don't Fall Down, which he calls "really, really good if you want a primer on structural design," Isaac Asimov's Foundation series, and Nick Bostrom's Superintelligence, which Musk warned is "potentially more dangerous than nukes."

He returns most often to The Hitchhiker's Guide to the Galaxy by Douglas Adams, which he calls "really sort of an existential philosophy book disguised as humor." He has also singled out The Moon Is a Harsh Mistress as "Heinlein's best book, honestly."
Most come from his posts on X, formerly Twitter, supplemented by interviews and talks including the Rolling Stone profile, a KCRW interview, The New Yorker profile, and the MIT AeroAstro symposium.
He has repeatedly flagged AI-risk titles, urging readers to read Superintelligence by Nick Bostrom, which he called "potentially more dangerous than nukes," along with Max Tegmark's Life 3.0 and James Barrat's Our Final Invention.
His recommendations gather around philosophy, society and politics, and science and technology, with a heavy strand of history and a deep affection for science fiction from Asimov, Heinlein, and Iain M. Banks.
