While I agree that the OLPC should be part of a larger effort to improve and fund international education, aid, and especially debt relief – your position is sadly naive.
It’s basically like the old choice of either helping by giving out food or by giving them the means to provide themselves with food. But in this case it’s about tapping into very powerful intellectual resources. The most important part of the OLPC is not the hardware, it’s how the software maximizes the hardware for collaborative learning, exploration, and culture bridging.
Also the role of organized religion in your post is flawed. Programs run by a certain faith push that faith’s interests above others. Higher paid Christian teachers using brand new bibles will not help children think for themselves, collaborate freely, learn all they can learn, or bridge cultural gaps without prejudice.
An XO in their hands however can allow them to learn about the world (wikipedia, etc) and with the world (chat/collaborate with children in other countries) in the most rapid, transparent, and diverse way in history. The software can not only maximize the hardware their given, but also the teachers, school materials, and anything else surrounding the child who’s using it. An XO can make a more empowered teacher that much more effective.
Your only valid point is that not everyone needs a computer. This is true. But there are millions of people.. mostly children, that could significantly benefit from having the right kind of computer available to them. Their future is the world’s future. If we are to overcome the real and present dangers that threaten our very existence (global warming, resource depletion, economic oppression, fascist oppression, etc) then we need to create the best tools we can for our children. No one will be able to save them but themselves.
