I don't understand why Japan is so obsessed with creating androids, while (arguably) the most essential technology behind enabling interaction with humans; the AI field of Natural Language Processing is being glossed over (or at least not getting the amount of attention it deserves). Not just computers, but humans too (and Japanese people in particular) tend to have great difficulty handling the barriers that foreign languages pose to vast amounts of useful foreign data. A successful grammar independent NLP framework for data representation, now that should be a goal to focus on. Everywhere, but in particular in insular countries like Japan. Sorry for wandering off topic...
