Assuming that C is the most successful language of its generation, among those letting purposely do anything with memory access, well, it's unfortunately possible to have it do anything. It's like saying with surprise that a harpoon gun may even kill people.

Then successively implemented languages may have improved things (or they would have been useless efforts). When a single one of them will reach half the popularity of C (without running in any "unsafe" mode) it will be another great success.

The original article was clearly just a polemical overkill by a maniac of another language. Or by a fisherman who kills fishes slapping them.
