At her Rock & Roll Hall of Fame induction interview backstage, Sheryl Crow told reporters that AI inspired her to write a song to deal with her fear of the technology. Sheryl Crow found inspiration for her new album from artificial intelligence, though she said the technology left her "terrified." At her induction to the Rock & Roll Hall of Fame earlier this month, Crow said she hadn't intended to do another album, planning instead to just release songs. But then "when the whole AI thing started coming out, particularly with the Beatles thing, and also having witnessed how AI is being used in my art form, I wrote a song about it." She continued, "I was terrified, and where do I go when I'm terrified? I go to my studio," adding, "And I found myself writing just one thing after another, and lo and behold I had 10 songs."

For the first time ever, NASA has been relying on private companies like Elon Musk's SpaceX for re-supply missions; only that's just the beginning. This QuickTake examines the future of space tourism using private space taxis.

The entire scope of the digital age – from the birth of the internet, to artificial intelligence, to catastrophist predictions of the end of days – is crammed into 96 idiosyncratic minutes in this latest documentary by Werner Herzog. And while Herzog's defiantly esoteric line of commentary works with some subjects – suicidal penguins, for example, in Encounters at the End of the World – he does seem out of his depth at times while navigating this vast and complex subject. Herzog's USP here is that, as a luddite who doesn't even carry a mobile phone, he is essentially a technological tourist, an outsider looking into the digital world. It's a sporadically fascinating film that dips its toe into many different themes where perhaps it should have chosen to immerse itself in just one or two.

Werner Herzog's films have a common theme: they're about visionaries and dreamers. Sometimes his dreamers accomplish the impossible: he's made two films, for example--"Little Dieter Needs to Fly" and "Rescue Dawn"--about the American pilot Dieter Dengler, who escaped from a Laotian P.O.W. camp and, for twenty-three days, hiked barefoot through the jungle until he reached freedom. But Herzog is also fascinated by delusional dreamers. At the end of his 1972 film "Aguirre, the Wrath of God," the conquistador Aguirre stands on a raft in the Amazon. He's been searching, fruitlessly, for El Dorado; now all his men are dead, and he's speaking only to their corpses and some monkeys.

To make a documentary about the Internet requires nerve. To do so when you can hardly be bothered with a cell phone, however, takes both innocence and bravado, plus a pinch of madness. All of which means that Werner Herzog, now aged seventy-three, is right for the job, and the result is "Lo and Behold: Reveries of the Connected World." The movie is divided into ten parts, none of which could be mistaken for a commandment; Herzog's documentaries have always been fired more by marvelling, and by an explorer's ache to learn, than by any pedagogic urge to tell. If he were struck color-blind tomorrow, he would instantly embark on a film about Matisse.

Elon Musk has a well-documented fear of evil artificial intelligence, so it's no surprise filmmaker Werner Herzog sought him out for Lo and Behold: Reveries of the Connected World. Instead, the tech mogul is worried about A.I. that does whatever it takes to accomplish its task. "The biggest risk is not that A.I. will develop a will of its own," Musk says in a short clip of the new film obtained by Fortune. "But rather it will follow the will of its utility function or optimization function." Herzog, the man who made Grizzly Man, is more attuned to nature than future technologies.

It's entirely possible Werner Herzog could find philosophical wonders and dilemmas making a documentary about your shoe collection, but until then we'll have to settle for this prolific filmmaker's abiding interest in the vastness of humankind's dreams, desires and actions. His latest nonfiction foray is about no less than what's changed life as we know it these last few decades: that coursing, unseen river called the Internet. And though the German auteur claims to be a technophobe, "Lo and Behold: Reveries of the Connected World" is just the kind of percolating, wry probe we need into this fast-moving, digitally monopolizing age. Herzog ("Grizzly Man," "Cave of Forgotten Dreams"), a natural alarmist at the same time he thrives on humanity's boldness and invention, isn't the type of explorer who starts with a pre-arranged idea. What animates "Lo and Behold" is his questioning spirit regarding the Web's journey from host-to-host communications tool devised in a UCLA lab in 1969 to the scarily inter-reliant nervous system of today. But with Herzog's initially chronological approach, there's plenty of humor in the recollections of gray-haired pioneers like Leonard Kleinrock, who mentions how the first machine-to-machine message from the refrigerator-sized computer at UCLA resulted in -- what else? -- a crash.

On Wednesday, Aug. 3, 2016, Tesla reports financial results. SAN FRANCISCO - Elon Musk is gleefully pushing the technological envelope in the arenas of rocketry, transportation and solar energy. But when it comes to much-hyped and coming promise of artificially intelligent machines, the man at the helm of Tesla, SpaceX and SolarCity has deep concerns. In a video clip released Wednesday to Fortune magazine from German documentarian Werner Herzog's upcoming film about the Internet, Lo and Behold: Reveries of the Connected World (premiering Aug. 19), Musk is subdued as he explains how AI could pose a significant threat even if such technology isn't in the hands of dictators and criminals.
