It's not the most common situation for a founder to write a review that destroys the competitor's new product, but Oculus co-founder Palmer Luckey has never been the most conventional entrepreneur.
Yesterday Luckey released a review of Magic Leap's developer package on his personal blog titles "Magic Leap is a tragic pile" where he offered some compliments but used most of his words to mark shortcomings on the new the device while trying to remind everyone of all of the tip of the Magic Leap execs about existing AR technology and how they ended up running with a device that, in his opinion, only made minor improvements over the three-year HoloLens.
It is a number of graves he does in his review, perhaps most insightfully, he uses the tracking technologies used for the headset and controller, and notes areas where they actually return to the user experience. The Magic Leap One controller uses magnetic tracking, a system that is far different and generally more complex than the optical tracking systems that almost all VR companies, including Oculus, use. As you read the section where he destroys the lack of a clickable trackpad, it becomes clear that this is probably more than personal to Luckey.
Luckey has now moved past his VR days in professional sense (for the most part). His new company Anduril Industries is focused on creating border security technology, but he has still been a very vocal personality in the VR room with a hardcore hobbyist's reputation.
Much of this steak seems easy to identify. Magic Leap CEO Rony Abovitz has spent the last several years getting a lot of money while developing technology in secret and trash that speaks existing technology in the public sector. In Luckey's view, this has not been good for investment in AR / VR rooms where investors have had unrealistic expectations in front of those who may have reduced interest in other existing cos who took a more conservative approach to hyping themselves.  The most brutal tasks are reserved for ML1's display technology, as Luckey points out, is really nothing but what other companies have seen. While the Magic Leap team invented terminology to describe what they have built, Luckey points out that they did not solve what they claimed they wanted.
They call it "Lightwear". This is the part that has got the most hype over the years, with endless talk about "Photonic Lightfield Chips", "Fiber Scanning Laser Displays", "projecting a digital light field into the user's eye" and the Holy Grail promise of Solving the Vergence-Accommodation Conflicts A problem that has bothered HMDs for decades – in other words, to ensure that the eye's focus always matches their convergence, which Magic Leap has played as critical to avoid "permanent neurological deficits" and brain injury. It is even more important for AR than VR since you have to mix digital items with real items that are consistently correct.
TL; DR : The assumed Photonic Lightfield Chips are only waveguides paired with reflective sequential-color LCOS monitors and LED lighting, the same technology that everyone else has used for years, including Microsoft in its latest generation HoloLens. ML1 is not a "lightfield projector" or shows at any broadly accepted definition and as a bi-focal display, only resolves host accommodation conflicts in constructed demos that puts all user interfaces and environmental elements on one of two focus plans. Mismatch occurs at all other depths. Similarly, a broken clock shows the correct time twice a day.
He also takes on the headphone's small field of view, which honestly feels like a low-priced shot when comparing it with other AR headphones that use much simpler optical systems. The Magic Leap screen provides a viewing area that has been estimated to be about 40 percent larger than HoloLens, but is still a small box in someone's perspective.
If you felt that this was just someone once so hard looking at a large product, it's clear when Luckey tries to estimate the sale of the device by looking at the company's order numbering system.
The order for Magic Leap was very easy to find out the first few days after launch. I collect some order numbers from friends and compared the booking times, and I'm pretty confident in predicting sales in the first week. Unfortunately, they changed the system shortly after I tweeted about it . Based on what I know, it appears that they sold about 2,000 units in the first week, with a very high bias towards the first 48 hours. If I had to guess, I would put a total sales of well under 3000 units at this time. This is unfortunate for obvious reasons – I know over a hundred people with an ML1, and almost none of them are AR developers. Most are tech leaders, "influencers" or formerly adopting as working in the industry, but have no plans to actually build AR apps. This was a major issue in the early VR industry, and it was with tens of thousands of developers among hundreds of thousands of development kits that were sold! Multiplication of the issue of a few orders of magnitude will be gross for ML.
Luckey does not seem to want to publish any follow-up with this device, nor did he give his personal device to iFixit to tear down after playing with it for the review.
After the post went up, Magic Leap's CEO Rony Abovitz reacted in typical eccentric fashion, presumably compared Luckey with a sign from Avatar: The Last Airbender with more strange tweets to follow.
