Dear Tihamer,
Thank you for taking the time to read my essay, and for your comments. You certainly raise a lot of valid issues with the idea of education helping humanity steer the future: the challenge of making people value education (especially about "difficult" topics that deal with the issues we will have to face in the future), and the challenge of making sure that we teach the "right thing". I agree with you on both counts.
Your solutions are interesting: working towards a semantic "intelligent" web that can help us make the right decisions against our weak willpower, and the need to diversify off planet. I also agree that the optimal "21st century attitude" should be a blend of realistic optimism and a willingness to "work smart" to make things happen. Here's to the future!
Marc
