The Design of HoloLens 2

Holy technobabble batman

    which could otherwise throw the headset’s laser and mirror optic system
    just a picometer out of alignment and make you puke into a hologram

lolwut. The oxygen-hydrogen bond in a water molecule has an average length of 95pm. Discussing the "alignment" of macroscopic systems at that scale is meaningless.

    Any extra wiring was a serious UX concern, because, as Kipman puts it, in mixed
    reality, where a device is reading and responding to the movement of your eyes,
    head, and body at the same time, “the speed of light is too slow.”

Nothing worse than the dreaded 1ns delay for 10cm of wire, amirite?

TBH this sounds like an interesting device, but the breathless exaggeration smells like desperation.
