AI: The Good, The Bad and The Ugly

From Siri to Alexa to Watson, we are living in an AI world; it understands when we ask it to play our favorite song; it knows what book we will want to read next. AI can recognize the face of an individual, and the distinctive look of a cancer cell. It understands concepts and context. It can write a song that sounds like the Beatles. From the weather to the shop floor to robotic surgery, AI's massive processing power is far faster than the human brain in computational ability, and is progressing in conventionally "human" areas like strategic thinking, judgement and inference.
