There are several gaps in capability between headsets and glasses, which cannot be filled by any existing technology.
For example, consider field of view, which is a critical measurement of these displays. Typical specs are 120 degrees for headsets, 40 for glasses.
Headsets also perform very high performance rendering compared to glasses. The tiny <1Wh batteries in glasses are insufficient for that amount of work.
Glasses can't be expected to compete with headsets, much less eliminate them from the market entirely within a few years. It makes more sense to think of VR headsets and AR glasses as completely unrelated product categories.
