Why Are They Saving All Your Messages?

Someone is copying your encrypted messages. Not to read them today. To read them later. It's called harvest now, decrypt later. A US Navy submarine reportedly built to splice into undersea cables. The NSA and Britain's GCHQ tapping around 200 of them and buffering three full days of the world's traffic at a time. China's Salt Typhoon inside AT&T and Verizon for months. Storage is the cheap part: keep everything, and wait for breaking it to get cheaper. And it keeps getting cheaper. The quantum computer it would take keeps shrinking, everything sent before the switch to post-quantum encryption is still filling databases, and AI agents just helped break two encryption records that stood for 35 years.
