Amazon CEO Jeff Bezos wants to colonize the Moon. Obviously. Business Insider reported on his speech at his firm’s re:MARS conference. He told attendees that we have to go to space “to save the Earth.”

Bezos said that using the moon is all part of his plan to save humanity by helping build the infrastructure necessary for space colonization. “The reason we’ve got to go to space, in my view, is to save the Earth,” he said on Thursday. “If we’re going to continue to grow this civilization, we need to move — and I’m talking about something our grandchildren will work on and their grandchildren— and so on this isn’t something just this generation is going to accomplish.” And the moon turns out to be the perfect landing spot for our eventual space needs for a variety of reason, Bezos believes.

The Apple App Store and Google Play store are something of a duopoly. This is causing some anti-trust concerns within the U.S. Department of Justice. Bloomberg News looked at why the DOJ is starting to think about app store marketplace.

More than $100 billion was spent through these marketplaces last year. Apple’s App Store handled 45% of that, while Google accounted for 25%. In the U.S., the two control more than 95% of all mobile app spending by consumers, according to Sensor Tower data.This power means most developers must work with Apple and Google if they want to reach billions of smartphone users as customers. The companies take as much as 30% of app sales, creating highly profitable businesses — but also a rising chorus of critics who see an exploitative duopoly.
