The Amazon billionaire enthusiastically shared his predictions for what human civilization will look like in the future – with him personally helping to bring that future closer – during a talk at the annual Ignatius Forum in Washington, DC.

He expects vast cylindrical space colonies spinning to create artificial gravity for millions of residents to take over most industrial production. Meanwhile, Earth will be turned into a natural reserve with restricted access similar to US national parks today.

"This place is special, we can't ruin it," the founder of Amazon said of our planet.

"Millions of people will move from Earth to space over time. And that's the vision of Blue Origin – millions of people working in space," he said, referring to his own firm.

"Over centuries, most or many of the people will be born in space. It will be their first home. They will be born on these colonies, they will live on these colonies. They may visit Earth the way you would visit Yellowstone National Park," Bezos predicted.
