I think it's grossly unfair to label those who's lives
have been up-ended by the backwards incompatible changes of
Python3 as "haters". Most of these people did not want or
even need these changes, and they were just happy to be
using a language that was intuitive, productive and did not
distract them from solving whatever problem happened to need
solving at the moment.

Sure, i think all the changes are great (except for type
hints, and i'm withholding my judgment of async for the time
being...), and had these changes been a part of the original
language, Python would have been a better language for it.

Personally, i will not decide whether or not to migrate
until Python4, and i suspect i am not alone in this regard.
And if Py-dev feels betrayed by the community, well, they
should understand that we feel betrayed as well. We have
invested decades into this language, and to have our
investments ruined by changes we did not ask for is
devastating.

So, can we overcome this devastation?

Possibly.

But Py-dev needs to understand that breaking backwards
compatibility is no small thing, and they also need to
understand that alienating the Python2.X'ers is not helping
the migration to Python3. I assure you, this community
cannot endure another one of these "engineered natural
disasters".

One of the reasons we've been so loyal to Python, is that, at
least historically, we had faith in GvR's judgments. And
while his fabled time machine has saved our bums on more
than one occasion, these days, some of us are not so sure of
our capitan's navigational abilities, and are feeling a bit
like we are the unlucky passengers on the Titanic. Speaking
personally here, i know i could have overcome the backwards
incompatible thing _eventually_, but Python3, followed by
the introduction of type-hints has been such a earth
shattering 1-2-punch, that i'm really struggling to stay on
my feet at this point.

I mean, i guess i could delude myself and imagine that type-
hints don't exist, but that's about as realistic as ignoring
a giant dent in the side of my beautiful car. Sure, the car
drives just fine, but the ugly dent sours the experience.
