Pedro Domingos likes big ideas. He sets out to describe to us how computers can write their own programs. For example, there is the well-established case of handwriting recognition. This is a form of machine learning in which the computer is provided with sufficient examples (and a training set) to enable the machine to learn to do something. If you show the machine the number “9” written enough ways, the machine eventually becomes as good or even better than a human at recognising a handwritten “9”.
Unfortunately, he alternates between very sensible and clear description like this, and sweeping optimistic generalisations. Mr Domingos is in no doubt who the new masters of the world are going to be. In his potted description of commerce, he describes the how “the progression from computers to the Internet to machine learning was inevitable ... once the inevitable happens and learning algorithms become the middlemen, power becomes concentrated in them.” In fact, there is no future for any company without using machine learning: “a company without machine learning can’t keep up with one that uses it ... businesses embrace it because they have no choice.” That’s a very stern conclusion!
