I dunno, but it seems like the iPhone was a product of many technological advances coming together at once, and Apple's key addition was to execute it in a way that made it appealing to the masses. So, I don't expect Apple to make a teleporter, or home fusion energy, or something that doesn't exist. I expect them to take something that is possible, like VR/AR, like videoconferencing, like IPTV.. even just computers and cellphones, and to execute them in a way that makes them the best designed product in the industry. Lately, it seems like they've been failing to do that. At this point, it seems like they're just a fashion brand whose products lack a compelling advantage over their competitors' products. Apple needs a guy like Steve Jobs to raise the standards and drive the company to meet them. Under Cook, it seems like they're sliding into mediocrity.
