Additionally, while the author is correct that a bad developer is a bad developer regardless of toolset, it's much easier to completely fuck everything up in certain languages. It's quite easy to write code that allows for buffer overflows or XSS vulnerabilities in some languages, and not quite so easy in others.

The important thing, to me, is that the language's path of least resistance leads you to The Right Thing. This generally improves quality of life for good devs and reduces the amount of harm bad devs can cause.
