Why Smart Glasses Are So Hard to Build ft. Karl Guttag, Writer and Analyst
Charlie, Ted and Rony open with a packed news week, covering the election results and the growing backlash over data centers, the XREAL Aura finally shipping, and hands-on impressions of Snap’s Specs. They also discuss layoffs at Schell Games, Beat Saber dropping support for older Quest headsets, Instagram’s new Edits app, and Rony’s new Fast Company piece on computational democracy. Karl Guttag, a longtime writer and analyst who was recently inducted into the AWE Hall of Fame, joins for a long overdue conversation. Karl traces his path from designing groundbreaking chips at Texas Instruments to becoming one of the sharpest voices on wearable displays, then explains why AR optics remain so difficult, with dozens of unsolved problems that all affect one another. The group digs into waveguides and the search for alternatives, Karl’s famously skeptical take on Magic Leap and Rony’s candid response, and where the real markets for smart glasses are today. Karl closes with his verdict on the XREAL Aura and Snap Specs.
