Yes, there are 14 languages on the list that are more productive than Smalltalk. However, one of them is a spreadsheet language. Another is a language used in a very narrow medical application niche. Another is a highly specialized mathematical language.

I always say “Smalltalk is the most productive of all the major programming languages in the world.” By “major,” I mean well-known and widely applicable. I am allowed to use this hyperbole because I am marketing Smalltalk to the public.
