There's more to a language than just features and functionality though. Why does Clojure have adoption despite being the least powerful Lisp, created decades after Common Lisp? Its stdlib, default data structures, and even syntax make it compelling (yes, sometimes having a deliminiter other than parentheses is helpful, and no being able to define new syntax via macros is not the same thing because defaults are important). Its not bad to rehash language features that have existed for 50 years if the resulting language has other compelling qualities.
