Mark Zuckerberg, Meta's CEO, believes that smart glasses with holographic displays will gradually replace mobile phones as our primary communication and computing device. In a recent interview, Zuckerberg shared his vision for the future of technology, highlighting the potential of smart glasses. He suggested that while these devices wouldn't entirely replace smartphones, they could become useful enough for most people to keep their phones in their pockets most of the time. Meta is currently developing three separate products, including a "displayless" glasses product with voice AI, a "heads-up display" without full holography, and a "premium version" with a full field-of-view holographic display.
