Roger Ebert, Ver. 2.0

I marvel daily at technology, and struggle to keep up with its opportunities and ramifications, and that's my business. 

There are moments when I forget how powerful and energizing technology is, and times when I just want to jump off the grid into a forest of silence free of USB ports and wifi connectons.

Then I watch things like this TED speech from film critic Roger Ebert, who lost his jaw to cancer and survived several related brushes with death. Ebert, a Pulitzer Prize-winning film critic and longtime PBS star, can no longer speak. But he's wired optimism to technology and the result is an inspiring message that should remind us all that when our backs are against the wall, opportunity lurks.
