Perhaps you should take your own advice.

There have been many new features added to computer languages over the 
decades, and some of them have been backward incompatible. Python has 
added new features over the years: nested scopes, decorators, new style 
classes, etc. Those who don't upgrade can't run programs written for the 
new version. Those who want to run programs written for the new version 
will upgrade. Python is going through one such change *right now* with 
Python 3. Other languages have gone through similar changes in the past, 
and will continue to do so in the future.
