You&#x27;re not going to find the technical truth on this blog. Look at the history of posts; the author clearly believes that Magic Leap is fraudulent at its core and wants to prove it. Everything Magic Leap does&#x2F;says is attacked from that inherently biased position. Any facts or data presented on the blog will be with that goal in mind, and any facts or data that support the opposite will be downplayed or omitted.<p>I don&#x27;t know whether Magic Leap actually will produce anything of merit, but this blog won&#x27;t help anyone find out.

Another post from today, really laying out the math behind hi-res FSD being a bad joke.<p><a href="http:&#x2F;&#x2F;www.kguttag.com&#x2F;2018&#x2F;01&#x2F;06&#x2F;magic-leap-fiber-scanning-display-fsd-the-big-con-at-the-core&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.kguttag.com&#x2F;2018&#x2F;01&#x2F;06&#x2F;magic-leap-fiber-scanning-...</a><p>Key point...<p><i>Thus the fiber needs go 10.17 meters X 240&#x2F;sec = 2,400 meters&#x2F;sec. For reference, the speed of sound is a mere ~343 meters per second (varies with temp and air density) so the fiber has to average about 7 times the speed of sound and because it is accelerating and decelerating back to zero at each end, it has to have a peak velocity of greater than 14 times the speed of sound!!!!!</i>

I thought Magic Leap had already waived the white flag and decided to become yet another goggle vendor.

Also Moore&#x27;s Law in this context doesn&#x27;t even seem to make sense, the &quot;Law&quot; deals in transistors, not optical technologies.

&gt; But everything I can see as an engineer says that Magic Leap’s display hardware is not going to have very good image quality and it is going to be expensive to make.<p>So what? What are we supposed to take away from this?<p>Even if true, its clearly not stopping them, and its not clear if that will or will not make a successful consumer device.<p>If its rubbish, a few of people will lose a lot of money and we’ll all move on with our lives a bit disappointed, but otherwise not really caring.<p>The sooner they ship whatever it actually is, the better.<p>This kind of idle speculation is just gossip.
