Good point - I was unaware of just how much money Disney invested in MagicBands instead of elsewhere! I understand your comparison better now; if MBs are supplanted by mobile devices, it'll be another expensive, tech-heavy project that was fun for a few years but just didn't take off. Still, Disney is very unlikely to write off such a large investment for a total loss. Perhaps Shanghai will be used as an experiment, to see how well mobile devices would work instead? Maybe MBs will be updated to work in tandem with mobile devices? There's a lot to pros and cons on both sides - it'll be interesting to see what happens!
