It's interesting what "popular" can mean. Chances are the "popular" kids in your high school weren't necessarily well liked, they just had social clout.
Where I work now the the "Java" devs code about 80% Kotlin and 20% Java.
At my previous job we were mostly Ruby except for a service that relied on a Java library that connected to some obscure systems that no other language had a library for. Yeah, we used Java, but it was because that was our only option.
