The article IF true is showing that the direction of the R&D department is being misguided. Just look at what other companies are “trying”. Lenovo just showed off “Project Crystal” a laptop with a transparent microLED screen, and XReal has true AR glasses, that can go from fully transparent to “sunglasses”, and have a BETTER battery life than Apple Vision Pro. Apple is to playing it safe and no longer, THINKS DIFFERENT.
The mistake your making is assuming the article represents the sum total of apple’s research.
