Who a couple of decades ago would have thought this possible?

I quote from an article in the current Special Report on Internet Security in The Economist:

Cisco, a tech company, reckons that by the end of this decade there could be some 50 billion things with web connections (see chart 5). Among them will be lots of consumer gear, from cameras to cars, fridges and televisions.

The World Wide Web, which brought us websites and browsers, has changed our lives. Perhaps the Internet of things will do so again.
