Eu gosto disso. Vou fazer uma lista, aos poucos (work in progress), mas como traçar uma linha do que é popular ou não? Rust é popular? Poucas pessoas usam ou usarão, muitas falam dela. Zig é popular? COBOL é popular? Lisp? Qual? BASIC hoje é popular? Vale dialeto? Tem que estar ativa? Excel conta? Ela é popular, mas as pessoas acham que não é PL.

Quer ajudar completar a lista?
A maioria dessas linguagens serve para aprender novos mecanismos e formas de pensar, nunca serão usadas de fato. Algumas tem coisas boas, outras não, só é o gosto do criador. Não que isso deva ser menosprezado, mas muitas delas não tem nada inovador, só o mix de features é diferente. E a maioria não serão popualres porque falta uma feature importante, a popularidade. É difícil quebrar esse ciclo.
Farei algo que muitos pedem para aprender a programar corretamente, gratuitamente. Para saber quando, me segue nas suas plataformas preferidas. Quase não as uso, não terá infindas notificações (links aqui).
