I agree with the author's point about QR codes mostly leading to advertising. When QR codes first became popular, I was snapping pictures of everything to get a glimpse of the fascinating world hidden behind these squares. Now I just think it's going to lead to yet another pitch to separate me from my money, so they mostly go ignored. I also agree that in our fast-paced world, the QR standard is likely to be a lot more ephemeral than people might think (even if the Microsoft solution is not a worthy successor). I think most of the author's other points are fairly weak. Say, inventing a new encoding that looks snazzy but is still recognizable as a code sounds like a cool side project. If only there were more hours in a day. :)
