Even if they did make the world's greatest AR hardware of 2020, they wouldn't have a great product because they wouldn't have clear use cases to sell it, and it would be too hobbled by resource constraints of the available tech - much like pen computers of the 90s.

If it were the scifi-like AR glasses of the future, perhaps that would sell itself due to all the dreamed up ideas in movies and tv, but that's pretty far afield of what's possible today.
