There are many applications that, together, may make it worthwhile to wear AR glasses:

- Laptop monitor replacement or augmentation

- Indoor and outdoor navigation

- Identifying an available self-driving cab and dropping a waypoint for it to navigate to

- Immediate POV recording + sharing of ephemeral events (many people will like this, even if the HN crowd won't)

- Shared viewing of footage, large 3D graphics, or news items with your friends no matter where you are

- "Digitalized" brick and mortar fashion stores where you can easily identify clothes that fit you or that are in your price point. An enhanced view would show additional information, such as online reviews of each item.

- All the filtering features of the digital world can be brought into real life, including filtering out of advertisements

- Games games games. It sounds comical to say, but Pokemon will become real. People will run around with poke balls that release increasingly intelligent digital creatures. In Harry Potter AR, people will be able to cast digital spells by waving their wand in a certain way and saying the right thing. WOW or Runescape players could dawn their achievement capes irl

- Aesthetic landscape transformation. I imagine there will be a "default view," "modified view," and "off view" of the world. If you go to Times Square and enable the default view, you would be immersed in a digital world curated by the brands that advertise there. If you use a modified view, you can see whatever you want, whether that's anarchist graffiti or cyberpunk renderings. In the off view, all advertisements and all screens would be rendered invisible

- Usable IKEA instructions

- Non-boring meetings at work with interactive holographic renderings of enterprise projects

- Remote guidance and instruction (enabling emergency plant maintenance by people who have no clue how to repair a broken pipe)

- Digitally enhanced classrooms. Imagine a physics lab with a 3D rocket or roller coaster sim overlaid with force diagrams.

- Multilingual digital tour guide bots that can explain every nook and cranny of a city for free

- Guided construction of elaborate, ML-generated Lego structures

That's just the beginning. There are probably use cases we couldn't even imagine yet, kind of like how some technologies that are out today seemed like science fiction 10 years ago.
