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.

All of that will be solved by miniturisation and advancement of tech.

I think you are short sighted (haha!) to think that headsets and glasses are different categories, and that headsets are not just a preliminary research phase to things in the future like smart contact lenses etc.

Let's not hand-wave field of view. Glasses cannot display anything outside the bounds of their frames, and therefore cannot have a field of view as large as a headset. No amount of miniaturization will overcome that limitation.

Contact lenses having the capability of a headset? That's just magical thinking.

This is like saying a Gameboy and a Playstation are completely unrelated. Sure they have their niche but there is massive overlap as well.
