In human behaviour there has never been such a change.

You walk toward the bus stop and there a long queue, you notice that in the long queue not one person is reading a book or newspaper or indeed talking to anyone else.  You realise that this is the case these days wherever you go, everywhere people with their heads down over their phones.

In such a short time span in the history of the world there has never been such a change in behaviour.

So are we all now the slaves of'  'Silly Con' Valley and all those 12 year old billionaire male geeks?
