Well, I've given talks on databases (Postgres), javascript (vue) and modern devops (k8s etc) at various Perl conferences in the last years, so I cannot agree.
In fact, I'm giving a small talk on Docker today at the Perl Conference in the Cloud, and also a lightning talk about a ~50 line tool to provide an async web server to post to Matrix. https://tpc20cic.sched.com/
Yes, there are a few people entrenched in old ways (and sometimes it pays off to not always use the newest tech), but there are also a lof of Perl devs doing current stuff.
