Exactly. Widely-used programming languages continue to be used even when the authors move to a new version.

Perl 5 lives on and is still developed and maintained: https://www.perl.org/get.html

Perl 6 became Raku: https://www.raku.org/

Python 2 is still in use, but officially deprecated: https://www.python.org/doc/sunset-python-2/

You could probably start a business maintaining a Python 2 distribution and selling support to businesses and organizations that rely on Python 2 and are not in a position to upgrade: https://www.activestate.com/blog/python-2-eol-report-card-is...

Uh, raku looks interesting, the web site is also quite accessible. Sad that it took so long, maybe Perl6 would have regained some territory otherwise.

Writing this while looking at CrewDragon docking at the ISS. Which took SpaceX 18 years, and many people thinking they would never make it. If anything, an inspiration to the people currently working on and using Raku!

And Larry & Co realised that it was sufficient different that now it is no longer called Perl 6.

and yet kept the logo that literally has P6 embedded in it

Perl5 is not EOLed, so no one is forced to "move". I haven't heard of any real business actually moving from Perl5 -> Perl6 (Raku, to be precise) for support/legacy reasons.
