I'm more than two decades away from being gen-z, and I still agree with that sentiment. There might be that theoretical wise and disciplined Perl programmer writing well structured and readable code, but wherever I interfaced with people writing/maintaining Perl code, it was the most hastily thrown together crap that once was a small tool that "just worked" and then slowly grew completely out of hands over the years. You can have that in any language, but for some reason Perl always excelled at that discipline.
"... but wherever I interfaced with people writing/maintaining Perl code, it was the most hastily thrown together crap"
The badly written stuff needs more "maintenance", and the people who need to work on it are more likely to complain (and I think you're stuck on confirmation bias).
In the late-90s, the early web gold rush was on, and a lot of amateurs started writing perl in a hurry as their first language. The fact that they could do anything at all is actually pretty amazing, and I'd say that's a point in perl's favor.
I think my comment kinda agrees with this, maybe I didn't make it clear enough though. You can write good or bad code in any language. But because of this, a low barrier to entry is both a blessing and a curse. And as time passes, and the more people touch the code, the higher the chances you end up with something cursed.
So my aversion to Perl could be considered a pragmatic solution to that problem. :-)
