The TIOBE index says Perl is currently the #11 most popular programming language (up from #30 a year ago). ref: https://www.tiobe.com/tiobe-index/
Now, I don't actually believe this, because that puts Perl way ahead of Rust (currently at #18). So the big thing I'm taking away from this little research post is that I no longer trust the Tiobe index. Too bad - it felt pretty reliable for a long time.
