SpaceX founder Elon Musk reminds us of Marvin from The Hitchhiker's Guide To The Galaxy. In addition to being a perpetually miserable robot from outer space (citation needed), he also has a brain the size of a planet. But how did he get so gosh-darned smart? DNA and upbringing probably had a lot to do with it - but so did reading the right books at the right age. Here are five books that Musk reckons everybody should read; from weighty science-fiction to breezy business tomes. Best of all, they're all mentally accessible to the average person.
At CES this week Samsung showed off a cute robot assistant for the home. It's called Ballie because, well, it's a ball. It's adorable and the way it rolls after people people is enough melt this cold, black heart. At least, it was until I realised its potential. After all, this little robot is a mobile camera that connected to and controls every smart home gadget in the house. Imagine the sinister things it could get up to.
