.......... We have phones now........
Ahh, that battle cry.
I recently had the millennial son of a boater holding his nifty little i-don't-know-much-phone in the air stating that marine VHF radios were passe' as a result of those little wonders being ubiquitous. When I asked him how his Dad will find the cellular number to notify that 900' freighter bearing down on his Dad in the channel when his prop shaft was damaged and he was dead in the water, he had not a clue as to what I was talking about.
Cellular service is not mission critical in any sense of the word, and is entirely built around 'blue-sky' situations....nothing special going on, sunny day, no weather events, no political events. One in 20 cell sites has a generator. Back hauls between cell sites are a mixed bag of whatever-carrier-is-cheapest data service, any of which can and are brought to a stop by a drunk hitting a pole.
My favorite example is a 2.5 Richter earthquake I experienced in Hawaii a while back. Just a minor tremor; most (including me) didn't notice it. However, cellular service was essentially nonexistent for nearly a day due to every person picking up their phone and calling someone else to ask what happened.
There are three types of people in the world....those that make things happen, those that watch things happen, and those that wonder what happened. As evidenced by the nationwide AT&T mobile outage of two weeks ago, the "we have phones now" people are card carrying members of the latter group.
