We were told to worry about quantum computing breaking cybersecurity.

It’s the right instinct. But it also means the organisations with the most resources get the best defences first.
Quantum was a slow-moving deadline. This is a different kind of urgency.
What is Mythos and why are experts worried about Anthropic’s AI model?
