All of the C versions post 99 or so probably have worse adoption. New versions of ALGOL, Visual Basic, Cobol. Being infamous isn't failure being unknown is a failure. Raku is a success I never have used Perl but I checked out Raku seems alright.
Perl 6, which failed so hard it's not called Perl anymore
yeah, but to be fair people had a gut-hate reaction to the word 'perl' before the update.
Perl ranks up there at the top of 'lists of programming languages people love to hate.'
