The Internet is a revolutionary technology comparable to the Gutenberg press. It offers direct communication between groups of people, bypassing the gatekeepers who have dominated and controlled the public conversations in the past.
Additionally, and just as important, through this contact with other people, we see them as similar to ourselves, rather than unknown, scary and hence a potential threat. The division into us vs. them that clans, countries, cultures and races encourage is weakening. The connections made through the Internet focus our attention on what we have in common, not our differences, and offer a way forward towards world peace.
