I hope you didn't read my comment as saying Python 2 is better. Personally I don't have an opinion on that. But as you can see from this thread and many, many others, a lot of people are disappointed with Python 3's choices. You're right, it's been a lot of years, but if adoption has been as slow as some are suggesting, maybe we could cut our losses and put our beloved Python on a different path, as a community.
Maybe, but at the same time I haven't yet seen a criticism of py3 that wasn't just a litany of complaints about backward compatibility. Even in this thread, I don't see a whole lot of substance behind the discontent.
