I'm not sure what argument you are trying to make. That in some putative future where AR headsets become a meaningful product category for wearable Apple might not be in a strong position?
I suppose for why you would have to take that context from the article; the argument that was in the "out there" parts of AR (e.g. glasses/goggles) nobody has shipped anything with real impact, but in the less flashy areas (e.g. assistive touch) Apple is years ahead. Plus a bit about M&A shifting apples capability in these areas. All sounds plausible. What this translates to in some potential future where more ambitious AR projects find a fit with consumers, who knows. But it terms of systems that ship today, article seems pretty accurate, and not at all deserving of your "what a joke".
True but not really germane.
