Their Orion glasses are apparently mindblowing in fidelity as well as the lightness of the glasses. Someone will absolutely make the smart glasses paradigm work so that we don't need to carry around phones anymore, and Zuck is racing to be first. This is because he lost out on the platform wars and was at the mercy of Apple and Google; remember Apple's privacy update that killed much of Meta's revenue? Zuck doesn't want a repeat of that by owning his own platform.
