Andrew Ng has always been ahead of the curve in seeing strategic shifts. He envisioned MooCs, founding Coursera to realise that vision. Then he helped found Google Brain. Then he helped Baidu become a leading player in AI (interestingly he pointedly says Americans are good at inventing stuff - Chinese at implementing it quickly. Sounds like the Imagenet cheating culture has't quite been eradicated yet -

So, by the sound of things, his next move is less technical and more political. How will AI change society and what vehicle would you use to help shape that change. Will be interesting to see what he does.
