Part of the problem with Innoventions is by the time someone takes the time to create a display for some wildly creative and innovative new thing, that thing is already obsolete, technology now moves that fast. Most of the things they used to showcase at Innoventions ("A way to turn on your oven and living room lights remotely...IN THE FUTURE!") can be purchased at Costco right now, and there haven't been any new wildly crazy things that a: have been invented that b: companies want to showcase at Epcot as opposed to, say, CES. And heaven forbid it's something in a very early test phase, that WON'T be able for years to come; what company wants to deal with their proprietary technology being out there for everyone to look at and copy before you've had a chance to profit from it? Oh, so WDW has something cool for people to look at on their way to Mission Space? Wow, that's worth it from a business standpoint!
Most of us have in our pockets right now a device that can access all of the information in the known universe, any song that's ever been recorded, billions of hours of movies and TV shows and kajillions of photos of cats looking up from boxes where they're trying to nap with snarky captions added underneath. It can amuse you, record pictures and video and audio. It can wake you up, lull you to sleep, remind you of things you don't want to forget from appointments to anniversaries, amuse you, challenge you, give you books to read, read TO you. It has more storage and RAM than my very first $1500 computer and is a heck of lot more portable at a tenth of the price. On any given day at WDW, as many people are looking down at their devices than they are soaking up the atmosphere and ambiance that people lost nights of sleep over in an attempt to grab your eye and spur your imagination. And it also makes phone calls. To an old fart like me, that's pretty much what the world's been leading up to. May as well make Innoventions a laser tag course.
Were it not for the fact that WDW has an entire park ostensibly set up to celebrate movies and TV, I'd say Innoventions would be great to showcase people new technologies being employed in movies yet to be reeleased. Then again, they're really not doing that sort of thing at DHS either anymore.
