Sorry if I did not make that clear but I fully agree that their endeavor towards better electrodes should be encouraged, and maybe even saluted when they provide evidence of improvement over the state of the art.
The question of information in the brain, including whether it is encoded is a really hard one. Of course we can easily find some areas of the brain whose response is _correlated_ with aspects of the outside world. But what does it mean? Who (or what) is decoding it, why? Many different metaphora and analogies can be (and are) readily applied to the brain. As of now, it is safe to say that a comprehensive theory of neural processing has not really been able to answer all of these questions. It’s just all very complex.
