As far as I can tell (and I may not be the best judge of that, because I've used a dozen languages over the past 25 years and still fail to see any really significant difference other than language philosophy as in OO, functional, etc), this is not about language quality but language safety. Those two are not necessarily the same, and some of the most elegant languages aren't particularly safe. Conversely, unlike people like to claim based on hearsay and no longer existing features, a badly designed language like PHP is definitely not less safe than Python or Ruby. By the standard for "good" set by the author, no dynamically typed language would make the cut.
