In my opinion, the measure of the value of new technology like this shouldn't be whether it has immediate practical application. Sure, it may not, but thank goodness people are still out there coming up with new ideas. Even if it doesn't have practical utility right now, who's to say that someone else won't see this, and be inspired to build on the idea to produce something that is immediately useful?
New ideas are what we need, good or bad. Just because we can't see something's value today doesn't mean that it won't be valuable tomorrow, next week, next year, etc. Keep on keepin' on, developers.
