I learnt perl for work related stuff in 1999-2000. Before that I had seen perl being used in shell scripting and CGI programs as a student. I had copies of Learning Perl and the perl CGI books. Perl was undisputed king of scripting and text processing.
As a programmer, I had looked at python and could not discern any obvious advantage in 2000-2004 period. Whatever python could do, perl could do more and had the vast CPAN repository. perl had more mind share, maybe also because of CPAN (People do not realize how big a deal CPAN was) People were still writing ODBC drivers in C, so the complexity of perl was not a huge deviation from normal affair of things. How was perl any different from Java AWT mess or complexity of SOAP?
Cut to 2025 and the world is very different. I have been training new folks joining from college and I do not think anyone has asked about perl in last 10 years even as a curiosity. After 2015-16 and ML boom, it has been python all the way. I am not sure where TIOBE is getting its data or methodology but young people sure are not picking perl.
