You must read "Hello World" by Hannah Fry

If computers, big data, artificial intelligence and self-driving cars confuse you, you should read Hello World by Hannah Fry. Hannah is a proper scientist with a wonderful writing style and she makes the technology easy to understand. She also isn’t afraid to muse on the dark side of all this shiny stuff.

There is no assumed computer knowledge, everything is clearly explained and put into context and subjects are introduced with engaging real-life stories. Everything is also properly referenced so that you can follow up on things that you find especially interesting. Excellent stuff.
