He was at the heart of 1960s counterculture, then paved the way for the libertarian mindset of Silicon Valley. At 87, Brand is still keen to ensure the world is maintained properly – not just today, but for the next 10,000 years

Stewart Brand thinks big and long. He thinks on a planetary scale – as suggested by the title of his celebrated Whole Earth Catalog – and on the longest of timeframes, as with his Long Now Foundation, which looks forward to the next 10,000 years of human civilisation. He has had a lifelong fascination with the future, and anything that could get us there faster, from space travel to psychedelic drugs to computing. In fact, he was arguably the bridge between the San Francisco counterculture of the 60s and present-day Silicon Valley: in his commencement speech at Stanford University in 2005, Steve Jobs eulogised the Whole Earth Catalog and Brand’s philosophy, and echoed its farewell mantra: “Stay hungry. Stay foolish.”

You could say that Brand has also lived big and long. He is now 87 years old, in the final chapters of an eventful and adventurous life that has crossed paths with some of the most consequential events and figures of his era. He has been a writer, an editor, a publisher, a soldier, a photojournalist, an LSD evangelist, an events organiser, a future-planning consultant, even a government adviser (to the California governor Jerry Brown in the late 70s). “There was a time when people asked me, ‘What do you do?’ I said, ‘I find things and I found things,’” says Brand, as in he is a founder. He is speaking from a library where he likes to work in Petaluma, California, not far from his houseboat in Sausalito. “I’m always searching for good stuff to recommend, and good people.”
