As world maps go, a globe is a much better representation than a flat map.
But as things are -- globes are hard to come by. We don't carry them with us. In the age of computing everything was on a two-dimensional screen. Some on-screen maps are improved by making them appear three dimensional (google maps does this), but still it's something on a flat screen.
Sculpture is more interesting than painting. Even the best paintings are those that make the art appear to be in three dimensions when it's not. Where the shadows are just right so it appears to pop off the canvas.
Up until now, everything nearly everything humans used to compute and record was in two dimensions.
You could get three dimensions in say an MRI by scanning different layers -- but then a person still had to have the skill to imagine it in 3 dimensions.
One of the things that you need to be able to do if you're an air traffic controller is look at a 2d screen and imagine a 3D world.
This will also allow computing to help everyone at every job...the computer will be truly portable and possibly with everyone much of the time.
This will be as profound as switching from handwritten books to printed books, or like the advent of radio and television -- or the arrival of the internet.
That's all about to change -- and this little company is a key to that change. Providing the near-eye displays and the scanners to make it possible.
Just watch.

Forget about your over-priced foldable smartphones, 5G networks that are struggling to set up, or the connected gadgets that have been heavily advertised at Mobile World Congress 2019 in Barcelona, Spain. The innovation that caused a sensation at the show is HoloLens 2, the new version of the augmented reality headset developed by Microsoft researchers, allowing its user to mix reality and synthesized images in real time and in relief, in its immediate environment.
