What Are You Optimistic About??

I know alot of people have reservations about the internet and its use, disuse or abuse adn whatnot...
Came across this book What are you optimistic about?: today's leading thinkers on why things are good and getting better Edited by John Brockman...nice reading especially the articel by Martin Rees entitled "Techo-Optimism and the Energy Challenge"
Techno-Optimism, very nice term. Alot of people are worry about Youtube, Myspace...and other social networking sites like them...
it is a great way for us to be connected, but you have to question the extent, the nature and the relevance of such artifical connectiveness or collaboration.
Reading Diane F. Halpern's chapter from abovementioned book "How Technology is Saving the World" and Nathan Myhrvold's "The Power of Educated People to Make Important Innovations"
That pretty much sums up my thoughts: Power, Education, Importance, Innovation.
