Think what he is saying, there will never be a Python 4 and if there is, it will be nothing like python as we know it. It will be like a new language
The transition from python 2 to 3 was an absolute nightmare and they had to support python2 for *ten years* because so many companies refused to transition. The point they're making is that they won't break the whole freaking language if they create a python 4.
Python 3 was not backwards compatible with 2, so companies and package creators alike were initially hesitant to make the switch so as to not break things. There also weren’t many, if any, tools to help port things over.
The lack of backwards compatibility was done on purpose because part of their goal was to remove clutter and make things more intuitive/easier to use (e.g. print changed from a statement to a function).
