Your reaction is actually quite common. Most people who learn Smalltalk absolutely love it. (Some don’t, because every programming language has its detractors.)
According to the StackOverflow developer survey, Smalltalk is the second “Most Loved” programming language in the world (after Rust). That’s saying a lot!
At Slant.co, Smalltalk was voted the best-designed, most concise and most productive programming language, beating out Python, Elixir, Scheme, and Nim. Wow! You can’t argue with the wisdom of the crowd.
