There's no "perl hype" because (virtually) nobody is just discovering it as something new and useful.
As python came to have a robust web ecosystem, it started to get a lot of hype as it was getting a ton of converts from perl/php/etc.
Now as web tasks are changing, Go's niche is becoming larger, and people are excited to use it where Python was failing them.
This will continue forever, most likely.
