The future is wireless, ubiquitous intelligence with billions of devices in an Internet of things (IoT).
Example: Facebook now has 1billion+ networked smartphones and people sharing within millions of interconnected special interest groups.
The Facebook algorithms are constantly intelligently evolving.
Driving this is both people and machine intelligence with increasing abilities to connect people to topics/ideas/forums (and vendors of products and services who pay facebook for the ads which increasingly closely match recipient interests).
