Yes, it does speak volumes about the language: Smalltalk is as close to the perfect programming language as you will ever find. After all these years, people see little reason to make big changes to the language; you don’t tinker with perfection.
Smalltalk is well worth evangelizing because it deserves great public attention. After all, this is a language that has been commercially used for over three decades.
Smalltalk is one of the most productive languages in the world, more so than Python or Ruby.
Smalltalk has a wonderful heritage, and it continues to influence IT.
Developers today get so excited about Elixir, Julia, Rust, Kotlin, Elm, Crystal, etc. Why not consider Smalltalk, too? It brings a lot to the table.
