Ok, fine. We are in full agreement here.

But then the post claims that "everything is a synchronization problem" seems should be qualified better.

Also, most of the comments before mine seemed to be in full agreement that yeah, full synchronization would be a silver bullet, even for cache invalidation

there's certainly things to sync in a airline app. Syncing the current schedules of flight is better than saying no flights exist when offline.

But when you're talking a about purchasing whats basically a live interaction with a paid for service, it runs into the verification/authentication aspect which can't be trusted by random customers.

So yeah, there's definitely apps that sync is a rare bit of concern to the customer/user experience.
