Bezos promises millions in space: vision or hype?

Bezos promises millions living in space: vision or hype?

Jeff Bezos has done it again. At Italian Tech Week in Turin, in front of Stellantis chairman John Elkann and with the solemnity of someone selling a certainty, he declared that "in the next two decades there will be millions of people living in space." This is no off-the-cuff remark: he framed it within his thesis of "civilizational abundance," a future where AI, robotics, and the space economy converge to take humanity off Earth. Ambitious. Or delusional. Depends on who you ask.

The reaction was swift. The investor community and seasoned skeptics focused where it hurts: physics, economics, and biology. Because dreaming of the Moon as a transit platform is one thing; turning it into a residential neighborhood in twenty years is quite another.

Bezos's dream: orbital data centers and lunar colonies

Bezos didn't just talk about houses in space. The core of his prediction is infrastructure: in 10-20 years we will see gigawatt-scale data centers orbiting the Earth, powered by 24-hour solar energy and dissipating heat with massive radiators. The logic is impeccable: computing demand grows without limits and Earth has an energy and heat problem. Space, on the other hand, is cold and sunny.

The most serious analyses admit that the debate will shift from "if" to "when" as the cost per kilo launched keeps falling. But the mass balance is brutal: millions of square meters of panels, tens of thousands of tons to put into orbit. Others calculate that, as of today, the Moon is only interesting as a "space gas station," a transit stop toward Mars or the asteroids. Mass colonization, according to this school of thought, is a 100-year project, not a 20-year one.

Thermodynamics, that stubborn thing

This is where the narrative collides with physics. Some sum it up in one sentence: "thermodynamics is very stubborn." Manufacturing anything in space will always be more expensive than manufacturing it on Earth: the energy needed to overcome gravity is non-negotiable. That's why the idea of "importing" goods produced in orbit sounds like a laughable economy. And biology doesn't help either: the human body is not designed for microgravity or cosmic radiation. Without a magnetic field or a thick atmosphere, life in open space is impossible. People would have to live in underground colonies or shielded structures, and even then, the cost of keeping a human healthy off Earth is, today, unaffordable.

Delusion or fundraising strategy?

The skepticism is not only scientific. One school of thought sees it as pure interstellar marketing: tech billionaires need to sell a splendid future to justify their megaprojects to the state and big capital. It's no coincidence that Amazon and Blue Origin have spent years raising public and private money for "the new frontier." The business isn't space, it's the promise of space.

And meanwhile, on Earth, the problems remain terrestrial: housing, public debt, inequality. Just ask those wondering whether, with the price per square meter through the roof, in twenty years it will be cheaper to buy in orbit than in a working-class Madrid neighborhood like Carabanchel.
