Since they were first theorized by the physicist Richard Feynman in 1982, quantum computers have promised to bring about a new era of computing. It is only relatively recently that theory has translated into significant real-world advances, with the likes of Google, NASA and the CIA working towards building a quantum computer. Computer scientists are now warning that the arrival of the ultra-powerful machines will cripple current encryption methods and as a result bring a close to the great bitcoin experiment—collapsing the technological foundations that bitcoin is built upon.

“Bitcoin is definitely not quantum computer proof,” Andersen Cheng, co-founder of U.K. cybersecurity firm Post Quantum, tells Newsweek. “Bitcoin will expire the very day the first quantum computer appears.”

The danger quantum computers pose to bitcoin, Cheng explains, is in the cryptography surrounding what is known as the public and private keys—a set of numbers used to facilitate transactions. Users of bitcoin have a public key and a private key. In order to receive bitcoin, the recipient shares the public key with the sender, but in order to spend it they need their private key, which only they know. If somebody else is able to learn the private key, they can spend all the bitcoin.

In Brief:

This newly developed bionic eye sends images directly to the brain to restore a tiny fraction of the pixels a normal eye can produce.

There are about 285 million people in the world who suffer from some type of visual impairment. For many years, researchers have been looking for ways to restore eyesight. This year, Australian volunteers are set to receive bionic eyes which should help restore their vision.

Rocket Lab is dedicating itself to launching small satellites cheaply and efficiently — a capability the American company thinks the burgeoning private spaceflight industry desperately needs.

Small satellites, some no bigger than a lunch box, are revolutionizing how people gather data about the Earth, and they might be the future of global communications.

Rocket Lab’s business model is a bit like Henry Ford’s was when he started selling Model T’s: keep the machine simple, produce a lot of them and keep them affordable. Peter Beck, the company’s owner, told Space.com that he’d like to reach a point where Rocket Lab launches one of its custom-made, small-satellite rockets about once per week. And similar to Henry Ford (who didn’t even want to make different colors of the Model T), Beck said that until that basic goal is met, he has no plans to diversify the company’s services.

Through the past few decades of summer blockbuster movies and Silicon Valley products, artificial intelligence (AI) has become increasingly familiar and sexy, and imbued with a perversely dystopian allure.

What’s talked about less, and has also been dwarfed in attention and resources, is human intelligence (HI).

In its varied forms — from the mysterious brains of octopuses and the swarm-minds of ants to Go-playing deep learning machines and driverless-car autopilots — intelligence is the most powerful and precious resource in existence. Our own minds are the most familiar examples of a phenomenon characterized by a great deal of diversity.
