If you take a look around, printed words don't exist in most languages. Most languages are spoken. Printing is an extremely new thing we've only had for a very short amount of time. The only thing print can do is present a stilted, over-formal version of what listening to a monotone person give a speech in a dark room might be like. That's good enough for most cases, since the brain makes stuff up it needs. But I don't think it's language, at least not in the same way real spoken languages are language. Real languages are a messy and confusing affair, even more than printed words can be. The way it works is through the interaction over time, not over definitions. (Something something language games)

I wish the guys luck. I'm not so sure we understand the problem yet. We may end up creating a machine that makes up answers to our questions after reading such that it sounds like a real person is doing the work. That's cool -- but it'd be a horrible disaster for humanity if something like that started being the primary interaction point with people. Over time it would make us a horribly stupid and unimaginative species. Like everything else in tech, we have good intentions and endless optimism. We're going to solve a problem whether we understand what it is or not, dang it. plus ça change... (And no, I don't think giving up the idea is any good. I'm just encouraging more understanding of the real goal versus the apparent goal)
