With technology advancing, Elon Musk is worried that if there aren't laws and restrictions placed on artificial intelligence that it would likely cause World World 3. He tweeted this in response to Vladimir Putin, who said that the first to become the leader in A.I. would rule the world. Elon wrote a letter to the leading robotic engineers and the UN asking for a ban on killer robots. He believes that AI could be more of a threat to the world than a nuclear war with North Korea, mainly on the fact that it wouldn't be country's leaders who decide to go to war. It would be the A.I.'s who could declare war if it believes that it is the best probability for success.
Google has began developing an A.I. where the objective is to gather as many apples as possible. They were given lasers and when the number of apple began to get lower, they would become highly aggressive to ensure it gathered the most. This may seem like no big deal as these are just dots on a computer, but as technology continues, we may lose control before we even know what we are dealing with.
