Except that Magic Leap's technology problem has had $1B in investment capital thrown at it -- much more than flying cars, no?
Looking cool on TV doesn't mean it'll sell. Movie OSes have every keystroke and action make a sound and use 48pt font for everything. I wouldn't bet much on such an OS selling in the market.
The tech demos are undeniably, but after "Wow!" my second thought was, "If I'm not a gamer, why would I buy this?"
And that means that first, they'll make it do enough desirable things that you will accept ads.
And those will make you want it.
I'm also a little disappointed they've raised so much money if their long term goal is just spamming people in "augmented reality".
