A 21st-century version of OS/2 Warp may be released soon

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.

If you're suffering from poor personal banking experiences, seriously look for a credit union. I do most of my banking with a mid-sized credit union, and they are exponentially more competent and better to deal with than any commercial bank.

On the commercial side, my wife was a finance director, and while she didn't handle payroll or borrowing, she did a lot of billing, receivables and some treasury processes at various times. Her employer used a "too big to fail" mega bank, a bigger commercial bank (at that time) and a regional player that was growing. The regional bank was better in every respect, they were hungrier for the business and because it was a newer/growing line of business, their processes were clean and reliable. The "too big to fail" bank was hooking together legacy crap from 5 different merged banks. Their priority was issues with Fortune 50 and .gov clients.
