That changes things… but not in the way many of the old Java fogies may have anticipated: It validates DHH’s point of view in the strongest way possible. Dynamic languages are a powerful tool in any programmer’s arsenal–if you get exclusively attached to Java [1] and ignore dynamic languages, then do so at your own peril.

[1] The idea of getting exclusively attached to a particular language/platform is silly–they are just tools. Kill your ego. Open your mind and explore new technologies and techniques so you can use them when appropriate.
