We now take for granted amazing educational resources such as Wikipedia, search engines such as Google, mapping systems, and all the myriad services of today's Internet. But we should not: recently at a OLPC trial, a parent asked "What is the Internet?"
The Internet, the web, and the community that has built these services are key foundations to enabling learning by more than a billion children. As we look forward toward to the web reaching billions more, many challenges become clear: the last mile problem, back-haul from remote areas, world wide content distribution networks, and offline access, to name a few. The web is indeed still in its infancy.
