The thing I don't understand about the demo on the web page is that, those students, they weren't wearing magic leap's device, how did they see the augmented whale? what did they cheer at?
Magic Leap is just setting itself up for an even bigger disappointment than everyone seems to be experiencing with HoloLens' highly limited field of view. The company is promising the moon here, without making any apparent concessions to limitations of the technology.
If they would just under-promise, I'm sure people would be blown away when they first try Magic Leap. The way they're going, though, disappointment is almost certain.
