Most Important Technology of the Last 40 Years:

The Internet.

Most Important Technology for the Coming Decade:

Still the Internet.

Technology That has Evolved in a Surprising Way:

Cellphone usage: the number of people who use them instead of land-line telephones. Also surprising is that the quality is still as poor as it is, and how much we all tolerate it.

"We're talking about having ubiquitous broadband capability to all homes and mobile connectivity that is high-bandwidth as opposed to intermittent. So the ability to access information anywhere, anytime, and the way in which the Internet will bring people together, regardless of where they are, will really have a profound impact."
