Imagine you're trying to pay for gas in a rural Alberta town, and the payment terminal goes down. Or you're on a remote hiking trail in the Rockies, trying to check your downloaded map, and your phone suddenly says "No Service." Maybe you're at a busy Edmonton festival, trying to pull up your e-ticket, and the network is completely jammed. These aren't rare, edge cases. They're everyday frustrations. Your app needs to survive these moments. It needs to work when the network doesn't. This isn't about being nostalgic for dial up. It's about building software that people can trust, software that doesn't abandon them when they need it most.
