Karsten Staack has put together a fascinating (if not disturbing) visual survey of technological projections for the 21st century:
Based on Peter Pesti's compilation "Detailed Roadmap of the 21st Century."
What I find interesting about this virtual tour is not the amazing new toys we'll all have, but the profound social, political, and economic implications these would clearly have for humanity. While I'm not convinced that any of these technological changes is a "done deal," I'd really like to see someone's take on what they suggest for the future of human freedom and identity.
