There isn't just one web. There are many webs, the one we call web is the information web that can be browsed. There is a web being built that is invisible to a browser, it is the web of machines - referred to sometimes as IoT. As usual it is being met with cynicism, because we are not able to see the potential of machine to machine communication. Machines don't have to be physical devices, they can software logic elements. The communication transport does not need to be heavy weight, it does not even need to run entirely over existing TCI/IP transport. Some of the possibilities of IoT are obvious i.e. call home feature, automated trading floors, intelligent surveillance etc. But some are not so obvious. Take for example, your TV prompting you to watch a program because it read a note on your blog or read your profile and "understood" that some program running now is important to you. (apple tv take hint please). Or it knows using face recognition using kinect who is watching the Tv and adjusts the shows according to preference.
I would like the kitchen not just the refrigerator to tell me that the dish on today's cooking list does need an ingredient that I don't have or will run out of soon.
How about my shingles on my roof detecting the leak and sending their location so I don't have to spend hours on the roof with a bucket of water to find it.
Or how about my favorite.. ,(being the only guy I know who had to lost two cars to engine blow out because the engine did not enough oil and broke down) where my car simply decides that maintenance can no longer be postponed and using the yet to be developed or perfected driverless technology drives itself to a oil changer get its maintenance after dropping me at work.
Increasingly the innovation is in removing the human element from processes which ultimately makes the human more productive.
