Ever imagined data centers in space?

Amazon founder Jeff Bezos predicted on Friday that gigawatt-scale data centers will be built in space within the next 10 to 20 years and that continuously available solar energy means they would eventually outperform those based on Earth.

Speaking at the Italian Tech Week in Turin, Bezos also compared the surge in artificial intelligence (AI) to the internet boom of the early 2000s, urging optimism despite the risk of speculative bubbles.

The concept of orbital data centers has gained traction among tech giants as those on Earth have driven up demand for electricity and water to cool their servers.

"These giant training clusters, those will be better built in space, because we have solar power there, 24/7. There are no clouds and no rain, no weather," Bezos said in a public conversation with Ferrari and Stellantis Chairman John Elkann.

"We will be able to beat the cost of terrestrial data centers in space in the next couple of decades."

Bezos said the shift to space infrastructure is part of a broader trend of using space to improve life on Earth.

"It's already happened with weather and communication satellites," he said. "The next step is data centers, then other kinds of manufacturing."

Hosting data centers in space has its own challenges, including the difficulty of maintenance and carrying out upgrades, and the cost of launching rockets, as well as the risk that the launches may fail.

The executive chair of Amazon said the AI wave shares traits with the dot-com era, when massive hype was followed by a crash.

"We should be extremely optimistic that the societal and beneficial consequences of AI, like we had with the internet 25 years ago, are for real and there to stay," he said.

"It is important to decorrelate the potential bubbles and their bursting consequences that might or might not happen from the actual reality," Bezos said, adding that the benefits of AI are expected "to be broadly diffused and it will go everywhere."
