I would say, many people also look down on much more popular languages, such as PHP. Go is still an absolute niche language, even more niche than languages like Scala or R.
Meanwhile, as a non Java programmer, I've never seen a Scala app. I know about R, but nothing on my PC is written in it.
Agreed that PHP is massive in comparison to all of them.
One widely known Scala application is Kafka. Some parts of it are in Java, but actual core is still mainly Scala afaik.
You could say the same thing about excel macros. They are both tools for wrangling data, tools that will typically not be distributed to end users.
