Can the US Military Re-Invent the Microchip for the AI Era? 

The coming AI revolution faces a big hurdle: today’s microchips.

It’s one thing to get a bunch of transistors on an integrated circuit to crunch numbers, even very large ones. But what the brain does is far more difficult. Processing vast amounts of visual data for use by huge, multi-cellular organism is very different from the narrow calculations of conventional math. The algorithms that will drive tomorrow’s autonomous cars, planes, and programs will be incredibly data-intensive, with needs well beyond what conventional chips were ever designed for. This is one reason for the hype surrounding quantum computing and neurosynaptic chips.

That challenge has a sister predicament: the end of Moore’s Law. The integrated circuit revolution that gave birth to the modern computer, smartphone, and basically all of Silicon Valley is in its twilight. In the 1960s, Gordon Moore observed that the number of transistors per square inch on integrated circuits was doubling roughly 18 months. That won’t be true after 2020, according to Robert Colwell, formerly of the Defense Advanced Research Projects Agency, or DARPA
