This Is How They Tell Me the World Ends

Reads like a thriller. Until you realize it all could be actively happening on the device you are reading the book with ;-) Yikes
Zero days in connection with state intelligence agencies is a volatile situation with no easy answers. I suspect we need to end up similar to the privacy/encryption debate. Nobody gets super-keys to encrypted data, impossible to control to only the “good guys” (also my good guy might be your bad guy). Need to do same with zero days.
