Compare that to the progress of native development. Apple comes out with new cool things on iOS every year, whereas on the web it takes 5 years to get something new that is 10 years behind the native counterparts.
Everything the web runs on now is much more advanced than the computers of 10 years ago.
Joe's point he made a year ago is still true today, but it hasn't happened. "Browser makers need to go nuts with non-standard APIs and let the W3C standardize later"
