Examples:
Do we really have to use toilets that flush with potable water? Can we either use gray water for this, or come up with alternative solutions that require less water?
Do we have to shower using potable water? For example, I’ve seen technology for reusing shower water. See e.g. https://orbital-systems.com/ for one possible solution in this space.
There are probably lots of other examples where the use of (potable) water could be reduced.
It just seems to be so unreal that we are so excited about AR/VR, but we can't even make technology that gets us a decent haircut.
The key feature is that the default access isn't that of the user account, but no access to any given resource, unless supplied as a capability by the user. It is not the checkbox access right bits found in smartphones and tablets.
We need to be able to run mobile code without having to trust it. Capabilities allow this to happen. If implemented correctly, we should be able to get rid of virus scanners and that layer of band-aids when it gets implemented.
I'd guestimate we're still 5-10 years out.
What the iPhone did for apps, the SteamDeck will likely do for video games.
Looking back through history you can see that the average home has slowly become automated via; washing machines, dish washers, and more recently robotic vacuum cleaners.
Using this trend I believe there will be more home automation devices which will be affordable. Trash robots (deal with taking out the trash), gardening robots (tend to the garden), delivery robots (fetch deliveries from the front door).
The future is unknowable, but we do know that robotic devices are becoming much cheaper and applications of them within the home are limitless.
As soon as we have a non terrible, hip, commercial AR product by a company like Apple, expect it to blow up like crazy.
The use cases for AR are actually realistic and practical. Education, construction, healthcare, natural resources extraction, and so many other industries will benefit from it.
Just beat the ad tech companies to it, so when the hardware is finally viable you can flood the ecosystem with new water.
