Donald Trump envies anyone who can do things he can't.

The Russian Dept of Tourism has declared Ukraine its most dangerous destination. Many Russian tourists have disappeared there.

It didn't take long to recognise the shortcomings of the Soviet regime and to see the values of the free world.

Anything that we know how we do, machines will do better. Now, the key element of this phrase is, "We know how we do it." Because we do many things without knowing exactly how we do them. So this is the area where machines are vulnerable, because it still has to learn from some kind of experience. It needs something - at least the rules of the game. You have to bring in something that will help the machine to start learning. It's like square one. If there's nothing there, if you can't explain it, that's a problem.
