Elon Musk has revealed what he believes will be the cause of World War III.
The SpaceX and Tesla CEO posted a series of tweets on Sept. 4 explaining how he predicts artificial intelligence as the cause of WWIII, rather than escalating tensions between North Korea and the U.S., KTLA reports.
Musk's tweets came after Russian President Vladimir Putin commented on the importance of artificial intelligence during a national "open lesson" for students in Russia, according to CNN.
"Artificial intelligence is the future not only of Russia but of all of mankind," said the Russian president. "There are huge opportunities, but also threats that are difficult to foresee today."
"Whoever becomes leader in this sphere will become the ruler of the world," added Putin.
He also said it was important that no country have a monopoly on artificial intelligence advancements, saying that if in the future Russia led the world in AI development, then it will share that technology with the rest of the world, like the country is "doing now with atomic and nuclear technology."
"It begins," Musk tweeted in response to an article detailing Putin's comments.
"China, Russia, soon all countries [with] strong computer science," wrote Musk. "Competition for AI superiority at national level most likely cause of WW3 [in my opinion.]"
Though the U.S., China and India lead the world in AI advancements, Musk said other nations would use any means necessary to outpace them.
"[Governments] don't need to follow normal laws," he wrote. "They will obtain AI developed by companies at gunpoint, if necessary."
He added in another tweet that an artificial intelligence could initiate a war on its own "if it decides that a preemptive strike is the most probable path to victory."
Facebook founder Mark Zuckerberg responded in a Facebook Live stream to Musk's comments, saying they were "irresponsible."
"With AI especially, I'm really optimistic," said Zuckerberg. "I think that people who are naysayers and kind of try to drum up these doomsday scenarios -- I just, I don't understand it. I think it's really negative and in some ways I actually think it is pretty irresponsible."
Musk struck back, saying in a tweet, "I've talked to Mark about this. His understanding of the subject is limited."
Musk is involved in two ventures involving AI: Neuralink, a startup that will work on integrating computers with the human brain, and OpenAI, a nonprofit dedicated to researching AI.
"I was trying to really sound the alarm on the AI front for quite a while, but it was clearly having no impact," said Musk in an interview discussing Neuralink, reprts KTLA. "So I was like, 'Oh fine, then we'll have to try to help develop it in a way that's good.'"
