In the time it took to write that article he could have ported a hundreds of lines of python 2 to python 3. If people spent as much time upgrading as they spent time complaining about having to upgrade we would have made a lot of progress. Is creating a third version of python that is worse than the current one but can use old libraries a good way or is working on moving forward and developing the newest versions of our language the best way.

That's a pretty pointless argument for a variety of reasons. The biggest one is that there is no reason to upgrade because Python 3 does not have a business benefit for lots of people.
As a person maintaining open source code Python 3 for me doubles my work for zero benefit as I'm not using Python 3 myself.
As a person working in a company upgrading to Python 3 means that I lose compatibility to the ecosystem and PyPy. If I support both, then why not just continue using Python 2?
Aside of that, there is so much stuff in Python 3 that is barely reviewed because there are no users that it's really damn hard to argue that it's unconditionally a better language.
//EDIT: arguing with "if people" is not useful in general anyways because a system would obviously be most efficient if all actors in it, would share the same ideals. But that's not how the world works. You could use the same argument to ask for why we don't have world peace.
How about providing the name of the company or website so we can have a chance of judging how meaningful your use of Python3 is. So far I have only come across a few small startups and a few individuals using Python 3 in production and in all cases they were very trivial apps to build and most had none to just a couple of dependencies on 3rd party libraries.
I'm honestly interested in finding out at least one serious project using Python 3 in a production environment. Everyone I know that earns a living programming and does Python development refuses to run their apps in production under Python 3. Many of them are willing to provide Python 3 support for libraries they develop so it's not the case that they don't want Python 3 to be successful it just they are not willing to take the risk or can't make the change due to dependencies that are not supported.
Just curious, how much Python code base is related to web development? The reason I ask, it seems these type of arguments I see seem to center around Python being used among web developers. But Python is being used in so many different domains. So it may be true Python 3 may not be used a lot in production in the web development world, but in the scientific and data analysis world, Python 3 is being used widely. I don't have numbers to back it up, but at my Fortune 500 company, we use Python for data or statistical analysis. The Python 3 code we use, use the full scientific stack (et. el. numpy, scipy, matplotlib) without problems. We are using Python 3 for making critical business decisions, which include whether or not our company will issue million+ dollar recalls.
So basically I am trying to say that we should remind ourselves that Python is being used in other domains besides web development.
I work with web and computer games. Everybody i know uses Python 2. I have yet to see a company of significance using Python 3. In fact: i don't know of a single company using Python 3 I think.
