IE6/7 objectively sucks. One could argue Python 3 sucked more than Python 2 based on performance benchmarks even year ago. IMO both Python 2 and Python 3 are pretty messed up languages with similarly messed up libraries, and "pythonic" way is often meaning "idiomatic" in the ugly sense of the word. But I do Deep Learning, data science and stuff with Boto/MWS on Amazon, so I have to stick with it. However seeing all the warts Python 3 throws at me and a crowd of people nagging to switch all the time, I frankly don't see much value in switching from one set of warts to another set of warts, waste the most precious thing I have - time, and all that just to duplicate what I already had (and disliked developing in Python anyway, but it was the fastest way).
