How has the technology been available for decades? There are many requirements for useful headsets beyond just strapping a low-resolution screen to each eye. Even the Vision Pro at $3500+ isn't quite there yet: it's heavy, external battery with a short battery life, has a limited field of view.

The technology to make VR/AR useful for specialized applications has been available for decades. For example, South African fighter pilots had AR sights in the 70s, and the Soviets copied the idea in the 80s. The technology has improved over the decades, but so far nobody has found good mainstream uses for it.
