Moreover we don't have to cram all the silicon and batteries into the glasses themselves. Some of it, especially an extended battery pack, wifi and storage hardware, can be stored in a small, lightweight, slim-profile backpack that's wired to the AR glasses. Probably the rendering silicon too if the short-distance bandwidth between backpack and glasses doesn't induce too much lag. Wearing small backpacks and fanny packs while urban adventuring is not uncommon. AR companies could just bootstrap off that already existing "infrastructure" with small backs that can still carry stuff, but with AR tech also inside them.
