You're probably right that more lines of Python 2 are written today than are Python 3. But I bet it's like that for virtually every latest version of a programming language today. Python 2 will be kept around until 2020. Obviously there will still be companies using it after that date. But they have been given ample notice. I use Django with Python 3 and it's great. Admittedly, I don't need a lot of performance though. I really like Python 3 mainly for its more explicit treatment of Unicode. I believe the only way for Python to remain a success is if the community adopts Python 3 and puts in the effort to migrate away from 2. Once the community is there, organizations will follow.
