You must live a charmed life if you never need to dig up and make use of old ill maintained code. You must be truly blessed if you also have time to port all your dependencies (and then maintain those ports).
Most recently? The MKL optimizations from continuum don't work with python3 on osx.
More generally? Everyone I work with is writing python2.7. All of my code is in python2.7. Nothing in python3 is compelling enough to warrant the pain of switching.
If someone made a python2.8 that backported new things from 3.x to 2.x in a backwards compatible way I'd be all over it, but I agree with the article in the OP. Python3 asks an awful lot and doesn't bring much to the table.
