Not to everything but when dealing with new technology whenever you hear sweeping statements you can usually bank on them being proved wrong at least in part, eventually.
Consider:
When will the Web replace RL food? Being that the body takes in food for energy to run on its not all that far-fetched (Just not practical atm.)
We regulate electrical energy by use of the net. Power generation stations are monitored and run by networked computer systems. Imagine if through genetic research we are able to adapt the body to run purely from energy from any handy source? Leaving us to just supplement our energy diet with minerals and vitamins? It would be handy I would gather.
When will the moon be made from cheese? My guess is when Kraft Foods becomes wealthy enough to afford the Nanotech Research to make our Nearest Neighbor into a Spherical Billboard that dominates our nightsky. Of course they may have to fight the United Federation of Planets to wrest control of the moon from them but hey weirder battles have taken place right here on Terra firma.
When you learn to fly by flapping your ears? With the advances in genetic research don't be surprised at the things people will do to their bodies in the search to stand out from the crowd.
300 years ago if you walked around with a small box that emitted disembodied voices (cell phone) you would have been burned as a witch.
Its hard to imagine what changes will take place in 300 years hence being that the speed of innovation and discovery is proceeding at a breakneck pace compared even to just 50 years ago.
When will George Bush receive an Nobel Peace Prize? Never. He has the wrong letter after his Name. (If it was a "D" instead of an "R" then he would probably get one for some monumental achievement like chewing gum or tyeing his own shoes, etc.)
In a world where we can have pastel-hued dancing monkeys at the tip of our fingers

anything is possible!
