Too bad for them. The rest of us get improvements. I'm way tired of being forced to use old C++ compilers because "upgrading is non revenue generating work". If you think rewriting your code in some other language is easier than upgrading to Python 3 then good luck to you.
And modern C++ is still being held back for deathly fear of breaking ABI despite clear improvements it makes impossible. People here seem to underestimate the cost of keeping backwards compatibility forever -- either you change very, very slowly (C) or your change is a clusterfuck of disparate requirements that keep blocking each other (C++).
Of course, "We want this code to run forever the way it is" is a value option that a company can choose - just not with any language it wants. And somehow, people seem a bit reluctant to switch from Python to C to be able to keep running the same programs forever, guaranteed.
