It's not about whether people found the PC cool or not. I'd argue that PCs never became "cool". They became useful. Back in the command line terminal days the PC served no purpose for the "average" user.
That's the issue with AR/VR. What's the utility? Why does anyone need it? AR/VR fans are constantly tossing out these weird edge case uses for AR and VR on threads like this, but none of them are mass-market ideas. We've had AR and VR hardware on the market for many years now, yet the entire category remains extremely niche.
I'm not saying AR and VR are useless, but if Apple (or anyone else) wants people to spend thousands of dollars on a device, it has to serve more of a purpose than animoji video conferencing and consuming media. The average person isn't going to see the value in that.
These are the uses for VR/AR, many of which appear scalable to the masses to me:
- Replace existing screens with a more versatile virtual screen of any size, any angle, any amount, curved or flat, 3D or 2D, it can follow you or be stationary and returned to, and can be shared via other AR or VR users across the globe.
- Have holographic calls where people are in front of you in full human scale and you can notice the small social cues that you might miss over zoom, talking/interacting will be more natural than other digital communication, and just overall feel more socially engaging.
- Tour real world places in the past or present all over the world.
- Have concerts and nightclubs, sporting events, conventions, talent shows, movie premiers, talk shows, theater plays, conferences and other virtual events that you can attend with others live where your brain feels like you are there.
- Attend a fully virtual school or university where it can be like a magic school bus ride where you tour the earth and solar system in real scale or go inside blood cells, making learning more fun, varied, and hands-on, with the ability to eliminate physical bullying, travel, and have a wider recruitment range for teachers.
- See reviews pop up outside a restaurant with the menu laid out in front of the building and life-sized portions of food in hologram form.
- Enter a supermarket and have a path on the ground drawn to each of items on your list in the fastest order, and it could tell you the ingredients of an item without having to pick it up and look at the labels.
- Try on clothes at home to your exact size by using holograms and seeing the materials in different colors/lighting and with physics applied.
- Have a personal instructor (not an AI, a human) show up right in front of you to assist you in all sorts of things such as a personal fitness instructor who could virtually bend your joints to get you to more easily follow along.
- Have notes and visual guidance overlayed onto various tasks like assembling a chair with holograms showing the chair in different steps and an animation of how to get there, or cooking with timers floating on different equipment, ingredients required and the required sizes of those ingredients shown in 3D.
- Control the volume of any person speaking, like an enhanced hearing aid that would be apply to even those who have good hearing.
- Give yourself zooming functionality, night vision, and a prescription that changes based on your needs such as reading, computer work, driving.
