“To start with tribalism is falling apart.”
Actually I would say it is not. Originally the tribe was composed of a group of people who could be communicated with by a leader talking to all the members of the tribe at the same time, thus leading them. After viewing the demonstrations of Egypt and Iran, I think the tribe has become huge thanks to the Internet, Facebook, Twitter, etc. Hopefully this huge Internet tribe will not be fooled by something so primative as fundamentalist Islam, and will embrace modern thinking that can find solutions based on science and creativity for their problems.
You seem very intelligent, however I do not share your optimism.
fundamentalist Islam will use the Internet as a tool to spread their beliefs. They'll seize control of it, through terror if need be.
