No matter how incredible the software is, I don't see a solution for the core problem that they will need to solve: battery vs weight. It's revealing that there are no prototypes shown at all.

Very curious what their weight goal is and how they plan to deal with physics.

Yeah especially as they plan for it to be wearable. It needs to be light enough to comfortably stay on your wrist for a period of time. Taking the climbing example again, having even a few pounds extra weight on your arm makes things a lot more difficult. If they added battery packs which the Nixie could recharge from to compensate then it kind of defeats the point of it being wearable and so portable.

Would depend on how it's done, of course, but just because something is able to use battery packs doesn't force me to carry them with me all the time. Just having some I could keep in a car to replace quickly while 'out' would be sufficient for some (many?) use cases.
