Tech: why Silicon Valley's top AI boffins are obsessed with how young brains learn

My infant son is a supercomputer. I'm not saying he could beat a grandmaster at chess, a trick that tech companies roll out to show us how smart their machines are, but what he can do better than even the most advanced artificial intelligence (AI) system on the planet is to learn. Which is why he -- in common with all babies and children up to four years old -- has suddenly become of great interest to Silicon Valley. The top AI researchers, including those at Google, are turning to our little ones in their quest to make the next big breakthrough.
