My “smart” phone is rarely used as a telephone. It’s set to silent, all notifications turned off, blocks unknown numbers, transcribes voicemail and spends most of the day as a window to the world.
I’m not sure what, if anything, a “dumb” phone would add to my life, except more interruption, more administration to keep contacts up to date, and yet another device to charge and maintain.
Docker is not virtualisation, although it’s a common misconception.
A better way to think of it is a security wrapper around untrusted processes.
You can prove this for yourself by looking at all the processes running in a Docker host while one or more containers are running, you’ll see all the processes listed.
In other words, you don’t need a CPU capable of virtualisation to run Docker.
