That makes it 2021, one year after Python 2.7 free support ends, but two years before Red Hat commercial support for it ends.

I seem to recall Guido saying that if there's a 4.0, it won't be a major break like Python 3, whatever that says about the numbering scheme after 3.9.

Is 7 years enough to eradicate Python 2 the way we did for Python 1? Then maybe Python 4 can reclaim /usr/bin/python.

I expect not quite. Perhaps 10 years though.
