Changes

The collection of data online has been in the news a great deal recently: I doubt that many people were aware of the extent to which use could be made of information which we unwittingly (or even carelessly) supplied on sites which we had thought to be benign. The situation only begins to come into context when you realise that we are not those sites' ''customers'' but rather their ''product''.

I've touched - very briefly - on just a few of the questions which Harari raises. He considers all aspects of twenty-first-century life in considerable detail. I found it a slow read, not because it was difficult to understand (in fact I was constantly surprised at the manner in which he could explain quite complicated concepts and make them easy to understand) but because I kept rereading sections or reading them out to others. I developed a degree of certainly on some questions but there were areas where I'd previously been certain of my views but now realise that I don't have the full picture and more thought will be required.

I'd like to thank the publishers for sending a copy of the book to the Bookbag.
