The United States has an unfair advantage, as most of the popular cloud services, search engines, computer and mobile operating systems or web browsers are made by U.S. companies. When the rest of the world uses the net, they are effectively using U.S.-based services, making them a legal target for U.S. intelligence.

Schoolchildren are not taught how to distinguish accurate information from inaccurate information online - surely there are ways to design web-browsers to help with this task and ways to teach young people how to use the powerful online tools available to them.

The thing that changed everything for me was the Firefox browser. I was pretty bad when it came to computers - I didn't know how powerful the internet could be until I discovered tabbed browsing.

While in the early days of networks, growth was limited by slowness and cost at numerous points - expensive telephone connections, computers that crashed, browsers that didn't work - the rise of the smartphone has essentially changed all that.

I continue to meet people who have had their Web pages hijacked, their browsers corrupted, in some cases, their children exposed to inappropriate material from these dangerous programs hidden in their family computers.
