If the network idea should prove to do for education what a few have envisioned, surely the boon to humankind would be beyond measure. Unemployment would disappear from the face of the earth forever, for consider the magnitude of the task of adapting the network's software to all generations of computer, coming closer and closer upon the heels of their predecessors until the entire population of the world is caught up in an infinite crescendo of on-line interactive debugging.
-- J C R Licklider in 1968
