But I found his blog a couple years ago and have been reading it ever since. Karl follows VR/AR display tech obsessively, goes to all the shows/conferences and talks with all the companies - then does highly technical, in-depth write-ups of what's new and notable - which often includes his unvarnished opinions. His blog is read by basically everyone in the industry, so all the companies give him briefings and demos despite the fact he'll call it like he sees it. Which is why he's pretty much my go to source when any new VR/AR display tech gets announced.

Even more valuable to me, he'll mention when companies are lagging or falling short of expectations and he'll even speculate about where things could (or should) go. His blog is basically like having a buddy who's an expert industry insider who'll tell you what he really thinks over a beer - which is pretty invaluable if you're someone who's interested and technical but doesn't follow this space that closely. That doesn't mean Karl's opinion is always correct but it is certainly well-informed and usually supported with technical data - although he did say this post was just a quick note that a video was leaked. He'll probably have a real post after it's announced and a deep dive once he gets his hands on one.

Interesting fact: Karl's career was as a chip architect. He designed key parts of the the Texas Instruments 9918 - the first general purpose video display processor which was used in dozens of 80s computers and game systems including Sega Master System (and coined the term "sprite"). https://en.wikipedia.org/wiki/TMS9918 https://en.wikipedia.org/wiki/Sprite_%28computer_graphics%29 https://kguttag.com/2025/07/01/tms9918-the-first-sprite-chip... So yeah, he's just "some random retired guy with a blog" but a guy with 150 patents and dozens of published technical papers. But being some random retired guy with a blog, he makes little effort to be accessible to first-time visitors or do design, marketing, etc. You just have to read-in and when you do, you pretty quickly figure out this guy knows his stuff.
