It seems like the article may have confused two concepts from information theory. He talks about entropy (without explicitly naming it) which can be used to bound the best possible data compression scheme.

Data compression is not the problem with interacting with devices though. What he should be instead looking at is channel capacity, where the user is encoding information for transmission that the device will receive and decode.

Maybe that's too technical for the nature of this article, but oh well.
