University = starting point of knowledge transmission

I agree mostly, except for where we can help.

Approximately 1 billion people in Africa, half of whom are under 25 yo, that represents 500 million people.

Lets say 250 million under 12 yo.
Do you think it is possible to send 250 million xo ? I don't.
That's worth $50 billions of hardware (not to speak of other costs).
Can _we_ (foreigners) send/help enought teachers for 250 million children ? no.

So 250 million child, lets say 25 million bachelor, 2.5 million at university.
1 machine for 10 students, that's 250 000 machines in several hundreds universities. This is possible now. (the number are certainly wrong, but not that much)

And from these universities, _they_ (developping countries) will "produce" their teachers/programmers/biologists/doctors/... which in turn will create their educational content, and educate the whole continent.

We can help in universities, because math are math, and there the teaching languages are spanish/english/french/... so we can directly share our educational content and tools. This is not the case for early education, which is very cultural dependant,
