Two centuries ago Leibnitz invented a calculating machine which embodied most of the essential features of recent keyboard devices, but it could not then come into use. The economics of the situation were against it: the labor involved in constructing it, before the days of mass production, exceeded the labor to be saved by its use, since all it could accomplish could be duplicated by sufficient use of pencil and paper. Moreover, it would have been subject to frequent breakdown, so that it could not have been depended upon; for at that time and long after, complexity and unreliability were synonymous.
This is something we have to keep in mind when developing technology, particularly in academia. It's not just the technology, but whether it can be put into production in a cost effective and useful manner. And just because the time is not right now, doesn't mean that as capacities change, it can't be done eventually.
