What if we told you there was a computer that can analyze and respond almost instantaneously to data from any of its thousands of sensors. That it can also match patterns in that data, recognizing faces, objects, and spoken words, and put that information into context, swiftly learning from what’s happening around it to predict what may happen next. Now, what if we told you it could do all that on around 20 watts of power, less than the average lightbulb—would that sound like a stretch?
