In current cities, a citizen may own a house, a computer, a smartphones, a TV, a refrigerator, an oven, a gas or electric stove, a bed, a desk, a sofa and so on. But, not in the city.
About 90% of assets are owned and maintained by the city regardless of tangible or not. This page is about electronics as ABC cities are IT oriented.
Like other assets, most electronics are owned by the city including smartphones.
All electronics are cloud oriented.
The only exception is smartwatches and smart rings which are owned by citizens as their private keys. See ABC Authentication for detail.
Smart Ring
All electronics are linux machines booted in the cloud, by the cloud, and from the cloud.
There are as many linux distros in the cloud as electronic devices in the city.
All devices are remotely controlled robotics of which brains reside in the clouds.
The computing power of a device is meaningless as a device is just a dumb terminal of its linux distro in the cloud.
All the electronics and the cloud are connected by a 6G network.
Those are private keys to boot any electronic devices from smartphones to autonomous cars.
They store the private keys and ID cards of citizens.
Whenever booting a device, it generates one-time private key to prevent malicious middlemen attacks.
The city provides computers in various display sizes. The computing power of a computer is meaningless as they are cloud based linux machines.
A citizen can change her laptop anytime, and pays as she goes.
The production cost of a medium sized laptop is about $100 because there is no ordinary CPU, GPU, RAM, sound cards, HDD etc., but just display and keyboard.
TV is just a dumb linux terminal with a larger screen.
A car also is a dumb linux terminal of which difference from other computing devices is that it moves.
Though the looks of cars and washing machines are quite different, they are the same kind of machines: Washing machines are linux devices too. It's like a car with only one wheel, running but not moving.
Yes, they are linux machines too, and of course, cloud based. It's like a car without wheels, but with a display, two or three doors and an air conditioner. Its passengers are not human, but foods.
As the city provides three meals a day to its citizens, it need several large cold storage facilities and quite less ones for homes.
Cold Storage
Bicycles and skateboards are all shared among citizens, and they are linux machines too.
