Python 2 has an EOL in 2020. Why start a new project in a language that will have support dropped in ~4 years? If it isn't going to be around in less than 5 years, I'm not going to use it for new projects which have lifespans measured in decades. I've got projects still in production, almost unchanged [only changes were to update business rules], for 4 years. It moves millions of dollars a year. I sure as hell don't want to worry about OS support for it another 4 years.
