Yeah, agreed.

If you think of safety as defence against accidents and security as defence against attacks, there's a large natural overlap simply because "deliberately cause an accident" is the most obvious family of strategies for an attacker.

That said, this distinction between safety and security, between accident and attack, often gets lost in this sort of discussion, and for this particular thread, highlighting the difference, and how the two are sometimes at odds with each other, was more important than highlighting the overlap.
