at no point am I arguing whether python 3 is better or worse than python 2. That is an uninteresting conversation because the fact remains that less than 30% of all software is in python 3. Even when Google released Tensorflow, it was in Python 2 (and they employ core developers of Python). Do you seriously think anybody is thinking of dropping python 2 support by 2020 ? that will only create a fork. None of the core frameworks have upgraded in a decade. Look at Flask for example. So yes, I havent been using Python 3 much - there has been no reason to. the point I'm trying to make is how to get everyone on the same page. The reason Python 3 was api incompatible was because of the core tenet of one-true-way. All the functions you mentioned may be superior, but unless you give people a way to mix and match both in the same source , you will not have adoption. Or do you think Python 3 adoption has been successful ?
