You're being downvoted but I have to agree I don't see any real-world use cases for this. It's too dangerous to use while riding a bike and I'm not going to walk around with a helmet on, talking to a virtual assistant. It may be useful in some kind of industrial environment with AR applications, but then again a helmet is not the most practical/comfortable item to wear for long periods of time.

Honestly I think they’re using the helmet as a prototype for a smaller device that will eventually be built once someone solves the “wearable vision” problem.

Possibly, but I still can't imagine talking to a virtual assistant anywhere except while driving or cooking. I think a virtual assistant integrated with the head up display of a car would be much more useful than wearables assuming we can keep people from hacking them and turning them into a major safety hazard by watching youtube videos while driving.
