Ask anyone seriously involved in security - whether computer science related, or in general.
A thought experiment:
Think about the most important secrets a country can have - now think how they are still discovered by competing countries, enemies, etc.
As long as there are humans in the loop there is a known weakness.
We know about many famous cases of leaks - like the USSR stealing notes from the manhatten project. But I bet there are thousands of secrets which remain secret. We just don't actually know about them, because, y'know, they're kept secret.
This simply isn’t the case. There are plenty of secrets that every military keeps just fine. See how long we’ve gone without anyone ripping off the F-22? That’s not even a new airframe anymore.
This is EXACTLY what I was talking about. The tech that makes the F-22 an unmitigated terror of the skies is of utmost importance, so it’s still kept secret. The barriers around that information are obnoxious, but effective. What blood type a subsection of your military has is of much less importance. That’s why that data was stolen (See: OPM hack) and our best weapons remain secret.
There really isn't
