There is nothing more that can be productively argued about this topic. There will be analogies about how complexity is hidden in various domains (cars, computers) and how beneficial it has been and how users are happy with it. Those arguments are fine and maybe they are being made in good faith, but it doesn't change the underlying future truth:
Marketing will now be changed to reflect Google keywords, not URLs. "www." and ".com" will become meaningless. Google will have put one more level of distance between what the users type in the URL and even what they click in the browser and what is reflected in the address bar.
