The very first point in the article is about the capability of a wireless device to last ten years on battery charge, and the argument in favor is based on current technology ("I'm amazed at how little power is used by the wireless processors I'm working on now.")

The real question is about the wireless processors designed 13+ years ago (longer than the painting to allow time for it to hit production).

This thing was supposedly designed and enabled before the iPhone was released. The author does not present a credible argument.
