Do not mix up vulnerabilities (security) with normal usage (generally buggy SW), which is what I talked about. I explicitly called out vulnerabilities as the actual problem that calls for safe languages. For instance, you can have a library that works perfectly for any non-malicious/valid PNG image, yet have vulnerabilities for invalid, crafted files. In fact, this is almost always the case for any product. Only really bad quality software has issues with the happy expected path. But many more will have vulnerabilities in the unexpected paths.
