Hard agree. I'm really trying to figure out how to inject this idea into my friends' heads effectively. The main struggle I'm facing is how to convey the danger behind it. Why can it be deadly exactly? What can a program actually do to harm people, to the level where it's a risk of extinction or societal collapse?

Personally I didn't need to imagine a specific scenario to understand that there's risk, but I think it would help me convince other folks if I did.
