Nope, Python 3 is a sane upgrade to a sane language bringing many enhancements to the consistency and reliability of Python. And it is being used in many production systems already.
Claiming people have been brainwashed because you happen to have a different use case than them is not appropriate for HN, nor anywhere.
And speaking to your earlier point as somebody using Python 3 in production, says me. Nobody in here cares whether you in particular gets to see the advantages of the new version; but you don't get to say "nobody is using it in production", you don't get to say it's "forced down people's throats" when there's years-long support for it and you certainly don't get to say "no good reason at all" if you're the only one unable to grasp the improvements the language is getting.
