While the author of this post is content to list reasons why IPv6 sucks, a better approach would be to realize there will be a billion dollar market created from the switch. I am going to predict that at least one and probably 2-5 companies in the next YC class are focused on this problem.
The way things are going, there isn't going to be a majority changeover until the window is already broken. Then it will be done rushed and expensive; remember Y2K? Everybody keep your networking skills up-to-date, there is likely to be a short, sharp opportunity to make good money - probably in a year to four (if they do wait for things to start actually breaking, it will be a little longer before they reach that point).
Oh downvoters, you are so predictable. For the sake of clarity: I do not believe the change to be unnecessary. However, if I am wrong, then to create make-work on that basis is an utter waste. Happy now?
