There was a recent Dwarkesh Patel interview of Dario Amodei, CEO of Anthropic, who now have ex. national security people on their staff. He said that the assumption is that if a tech company has 10,000 or more employees then not only will you almost certainly have leakers, but there is also a high likelihood there is an actual spy among your staff. This is why they use need-to-know compartmentalism, etc.

I wonder what our success rate is in identifying industrial spies? 50%?
