it's a neat tech demo, but it's completely delusional to think these huge glasses that require a battery pack and a wristband to function are anywhere close to a functional all-day wearable.
headsets/goggles and all-day wearable glasses are entirely different product categories. they might some day eventually converge a little bit, but the tech isn't there even in this unobtainium prototype non-product. earbuds and over-ear headphones both exist despite overlapping in their core function. different tools are better suited for different usecases—even if there are surface-level similarities
