This is a good article but it's important to understand that vision doesn't necessarily trump implementation. Steve Jobs also had a vision of augmenting human intellect (one at a time rather than collective), but he's remembered for the things he built in pursuit of the goal, not the goal. Ted Nelson's vision for hypertext is also more transcendent than what we got from the world-wide web, but on examination it turns out that hos vision is flawed and unrealizable (in practice there is never a canonical reference for any text) while what we've actually built actually works.
