Despite heightened tensions between the U.S. government and Silicon Valley in the aftermath of the FBI-Apple standoff, the Department of Defense is increasingly looking to Silicon Valley to help it develop artificial intelligence capabilities. Just this week, Secretary of Defense Ashton Carter made yet another trip to the Silicon Valley, the fourth such trip since he took the DoD helm last year. During this trip, Carter visited the Pentagon new Defense Innovation Unit Experimental, or DIUx, facility, reported the New York Times. During a speech there, Carter again discussed his Third Offset strategy, which looks to high-tech weapons to give the U.S. military an edge of China and Russia in the future. The first and second offset, in case you are wondering, refer to previous eras in which DoD used technology to compensate for a smaller military – the 1950s use of nuclear weapons to deter superior Warsaw Pact forces and the 1970s and 1980s when the Pentagon looked to improved conventional weapons technology, such as cruise missiles, to compensate for a smaller force posture.
