Is it ? If we talk abour VR, yes, but there are a number of companies actually delivering AR products whose focus is on productivity. Some examples (but there are more) are
Microsoft with Hololens [1] Epson with Moverio devices [2] Sony [3] Vuzix [4]
Their oldest model are simple smart glasses, it seems to me that they are moving towards full AR. As a plus side, they don't look something that I would wear only inside the office of SV startup.
