Re: resilience
Completely agree with the point about smart devices - living in a rural area means I am absolutely certain there is nothing critical in my house that won't work without the external network connection.
However, mobile data is only a viable backup in urban areas (which, by the way, suffer far fewer service interruptions than rural ones). Out here, not only is the mobile network very slow, it is also very unreliable. There is only one cell site for the village, and its battery backup is very short. Certainly nowhere near the "2 nines" of backup that you mention.
