It doesn't seem right to ignore the increased popularity of better and more user-friendly interpreted languages such as python, which has since became ubiquitous even in spite of the python2-python3 transition.
Also, there was the inception of node, which brought javascript front and center.
In fact, among the interpreted languages that were popular 20 years ago, which ones besides python still hold some relevance?
Perl, whether v5 or v6, can't exactly compete with javascript or python in terms of ubiquity and user-friendlyness.
If Perl's learning experience is harsher, and in the end there's less demand and job prospects, why would anyone pick Perl over any alternative?
