A lot of people in this thread speculate that Raku (formerly "Perl 6") killed Perl. But I have yet to see convincing first hand accounts confirming that.
I certainly don't believe it. Everyone I talked to at the time who worked with Perl knew it would not go away: humanity had chained too much of the infrastructure of the internet to it. Someone would have to maintain it for many years to come, even if Larry's new experiment became a wild success. (Already back then people seemed skeptical of the experiment and hung back with Perl 5 waiting to see what came out of it before paying too much attention.)
I still struggle to understand why Perl went out of favour[1] but I think what another commenter wrote here might come close: for Unixy folks who know shell, C, awk, sed, Vim, etc. Perl is a natural extension. Then came a generation of programmers brought up on ... I don't know, Visual Basic and Java? and these were more attracted to something like Python, which then became popular enough to become the next generation's first language.
