If somebody says X language is better than Y language, usually there will be a fierce quarrel between two sides. If you're using certain language for a long time, you will be the evangelist of that language, and try to protect it unconsciously. Admitted or not, you have been trapped in a tunnel, that what you can see is constraint greatly. "The Shawshank Redemption" gives a good footnote on it:
[Red] These walls are funny. First you hate 'em, then you get used to 'em. Enough time passes, you get so you depend on them. That's institutionalized.
So before we're institutionalized too deep, let's learn something completely different - a language that not derived from C family, a language that leads you to a totally different mindset.
Erlang seems to be a good candidate.
