Possibly so in urban areas. Internet is already available everywhere. Sell dumb devices that can remotely log in to virtual devices. An LLM can connect to this virtual device and execute whatever action the user wants. Centralising compute resources this way means it's likely cheaper to offer huge compute to tons of users and so rather than buying a smartphone, you buy a monthly subscription to AI which can do everything your device does but you just need to speak or text to it. Sub includes cost of dumb device maintenance, securing the data you sent to the virtual device, etc.

Personal Computing as a service. Let the computer think for you.
