I'm not really sure what you mean by that, but I don't think it's relevant - it clearly wasn't exactly a success, but it did come first, and it was the same kind of idea, what was possible at the time.
the constraints they put on it , specifically fitting all of it into a normalish looking pair of glasses, meant that they really weren't going to be able to give it enough functionality to actually make anyone .. want it.
It is a much more appealing form factor to me than AVP though. I don't want to work at home with huge goggles strapped to my face. I don't want to video call with people floating in space who presumably can't see me and if they can I look ridiculous. I don't expect it to last/take off if it stays similar to how it is, personally.
But normal looking glasses with a sort of information overlay is much more interesting; especially now I have a prescription anyway.
