Perl: 37 years old
Python: 34 years old
@siracusa Not to be overly pedantic but didn't Perl 6 get renamed, so I think _technically_ "perl" refers to Perl 5, which is really quite long in the tooth? But yeah, it is kind of a silly juxtaposition, and I'm also saying this as someone who was still maintaining a large and critical code base that was all written in Python 2.7 at my last job. I can't imagine I'm the only engineer on earth with that problem.
