As others posters have commented, Python 2 will survive in the sense that there will always be some code running on it (and there will be a niche market for dark artists who can massage it). Python 2 will not survive in the sense that no one will be writing new code for it. Python 3 is already commonly used for new projects and it's scheduled to get several big boosts in that direction as Ubuntu and Fedora switch to it as the default Python.

The old meme that it's unsafe to use Py3 is not true anymore. Practically all of the big libraries work fine on Python 3 now. Py3 code is going to be dominant in new projects in short order if it isn't already, and it's plausible that new Py2 projects will be virtually extinct by 2020.
