I think this article suffers from an overly binary view of technology -- if it isn't market ready, it's vaporware. No, there's probably some real tech there (aforementioned demo), but miniaturizing / productizing is still a risk. I think the blowback has something to do with the marketing itself, and Abovitz's amazing idiosyncracies. Neither of those indicate anything about the tech, but (absent any public information) it helps fuel the hate.
And from what I understand about their likely approach, it's definitely more aggressive than the HoloLens. I don't personally think that nearfield focus in a headset is that valuable, but that's just a guess. If light field displays are the tech that takes AR over the top -- from curiosity to a new computing platform -- then Magic Leap is really well positioned, vis a vis a large lead and big IP portfolio.
Also, with ~$1.4 bn raised, they're too big to fail.
