The good thing is - you can explain it relatively easily... Do you walk around with such glasses all day? No. It is much easier to work on monitors (plural). For ergonomic reasons alone... Of course, there are advantages in terms of electricity consumption; However, I don't yet see how this will prevail in general. It is and remains a solution to the gap. Something like this might make sense for simple work. Games, endoscopies, watching a movie. But if you really do work on the computer, you will prefer a monitor. After the minaturization of the technology, I see more of a replacement for the Iphone or maybe Facetime - nothing more. Studio work such as sound production, film editing, programming or technical development work cannot be carried out in a really meaningful way. By the way, I also think that the level of technology of these glasses today corresponds to that of computers and the early 80s.
And there is another important point: before (if you go by what you write) all this would happen, the development of AI would already be so far along that it could take over large parts of this work.
I myself asked myself in the 90s why Ram drives have no battery support and different controllers (today's SSD) and I will be right even this time. Let's wait and see...
