Stephen Hawking, Elon Musk, Steve Wozniak and over 1,000 AI researchers co-signed an open letter to ban killer robots

More than a thousand artificial intelligence researchers just co-signed an open letter urging the United Nations to ban the development and use of autonomous weapons.

The letter was presented this week at the 2015 International Joint Conference on Artificial Intelligence in Buenos Aires, Argentina.

Tesla and SpaceX CEO Elon Musk and physicist Stephen Hawking signed the letter, alongside leading AI scientists like Google director of research Peter Norvig, University of California, Berkeley computer scientist Stuart Russell and Microsoft managing director Eric Horvitz.

The letter states that the development of autonomous weapons, or weapons that can target and fire without a human at the controls, could bring about a “third revolution in warfare,” much like the creation of guns and nuclear bombs before it.

Even if autonomous weapons were created for use in “legal” warfare, the letter warns that autonomous weapons could become “the Kalashnikovs of tomorrow” — hijacked by terrorists and used against civilians or in rogue assassinations.

To everyday citizens, the Kalahnikovs — a series of automatic rifles designed by Mikhail Kalashnikov — are better known as AKs.

“They’re likely to be used not just in wars between countries, but the way Kalashnikovs are used now … in civil wars,” Russell told Tech Insider. “[Kalashnikovs are] used to terrorize populations by warlords and guerrillas. They’re used by governments to oppress their own people.”

A life in fear of terrorists or governments armed with autonomous artificially intelligent weapons “would be a life for many human beings that is not something I would wish for anybody,” Russell said.

Unlike nuclear arms, the letter states that lethal autonomous weapons systems, or LAWS, would “require no costly or hard-to-obtain raw materials, so they will become ubiquitous and cheap for all significant military powers to mass-produce.”

But just how close are we to having usable autonomous weapons? According to Russell, affordable killer robots aren’t a distant technology of the future. Stuart wrote in a May 2015 issue of Nature that LAWS could be feasible in just a few years.

In fact, semiautonomous weapons, which have some autonomous functions but not the capability to fire without humans, already exist. As Heather Roff, an ethics professor at the University of Denver, writes in Huffington Post Tech, the line between semiautonomous and fully autonomous is already quite thin, and getting even smaller.

For example, Roff writes, Lockheed Martin’s long-range anti-ship missile can pick its own target, though it is fired by humans, at least for now. “The question has been raised whether this particular weapon slides from semi-autonomous to fully autonomous, for it is unclear how (or by whom) the decision is made,” she wrote.

According to the New York Times: “Britain, Israel, and Norway are already deploying missiles and drones that carry out attacks against enemy radar, tanks, or ships without direct human control.”

This open letter banning autonomous weapons is one of the latest warnings issued by scientists and entrepreneurs about the existential threats superintelligent AI could pose for humanity.

In December 2014, Hawking told the BBC that “the development of full artificial intelligence could spell the end of the human race.

In January, many of the signatories of today’s letter signed a call for AI research to remain “robust and beneficial” on the Future of Life Institute, an organisation headed by prominent names in AI research, scientists, and even Morgan Freeman.

The same month, Musk donated $US10 million to the Future of Life Institute to fund a variety of research projects that aim to do just that. The 37 projects includes one that hopes to ensure that “the interests of superintelligent systems AI systems align with human values” and another, headed by Roff, aims to ensure that “AI-driven weapons are kept under ‘meaningful human control’.”

Jared Adams, the Director of Media Relations at the Defence Advanced Research Projects Agency told Tech Insider in an email that the Department of Defence “explicitly precludes the use of lethal autonomous systems,” as stated by a 2012 directive.

“The agency is not pursuing any research right now that would permit that kind of autonomy,” Adams said. “Right now we’re making what are essentially semiautonomous systems because there is a human in the loop.”
