Without knowing how close things are to looking like the images in the concept video, it is no different than lots of other science fiction interfaces. I think there are lots of cool ideas, but implementation is what matters.
The problem is the design is the part that is most likely exactly as it is shown in the video, while the images of what is seen are least likely to be “as they appear”. That is why there is so much criticism of the design.
Like all new tech, it is all about the quality and integration of the implementation, rather than the top line description. A foldable display that was reliable, aesthetically pleasing, thin, light and integrated well would be cool. Unfortunately, no one is producing that. Same goes for this. Nice visuals, what will really matter is the actual product implementation.
