Granted, it still happened about a decade and a half ago, so I hoped the sarcasm using the word "new" would come through.
It did ;-) . But I frequently meet devs (young and old) that believe Python, Ruby and others are "new" languages. So I think it's worth mentioning they are not in any way.
Of course age does not equate maturity. Neither social acceptance.
