"I wished my banks were that reliable. I'm not sure whether 'open all the time except when DDOS'd' is a real improvement over a predictable paper based bank that simply always works." High-assurance engineer, Clive Robinson, and I both recommend paper over computers wherever possible for high-risk stuff. It's unhackable. The leaks require riskier action. They usually only take what they can carry. Destruction is expensive but straight-forward with cross-cut shredders. People know how to protect the stuff because it's same skills they're used to at home. And so on. Next thing to do is avoid Internet in favor of leased lines over VPN's if you can afford them. Boring-ass transactional processing on boring, well-maintained servers. Straight-up delete code you don't need out of the OS. App memory-safe using simple protocols. There's ways we can make it better on computers. Paper is still safer, though. Especially after decades of mitigations developed in response to people like Frank Abignale.
