Show Notes on Part 2

Karl Guttag writes a popular technology blog at kguttag.com where he dissects optics and display systems, including the efforts of Magic Leap. In this, the second of three parts of our conversation, Karl and I get into the details and tradeoffs of display technologies used in smartglasses. (For more on Karl, check out the previous episode.)

This episode is almost a masterclass in microdisplays.

In several years, you’re not going to care about the nitty gritty details of microdisplays. But if you are making decisions dependent on the timing and growth rate of consumer-grade AR smartglasses, you should care. The biggest barrier – the most important missing ingredient – to consumer-grade smartglasses is the display. Based on the technology available today, there is NO WAY Apple ships smartglasses in 2020. Karl estimates it’s going to take 5+ years for the display systems to be good enough. You’ll make better decisions about where and when to invest if you understand where the false promises are, where the real hope lies, and why it’s so hard.
