I understand the POINT of the article quite clearly: the point is the speed of obsolescence and the acceptability of ignorance to alternatives. What I'm saying is that the author is incorrect that all of the older alternative devices and methods that perform these functions will be completely obsolescent in 26 years, and the reason that they will not be is that the devices he is citing are mostly dependent upon the grid. Without electrical power, most of them become useless bricks in a day or so, and sometimes within only a few hours, and only an idiot like this author would blithely consign all manually operated alternatives to the dung heap just because they may not be the OPTIMAL tools for the job. Total ignorance of alternatives to the most popular methods and tools would leave an unacceptable number of people helpless in an emergency, so it is in all of our best interests to be sure that it does not happen.
I'm not talking doomsday scenarios here; I'm talking two weeks to a month without electricity. It can and does happen in this country, but when it does, our need to live, work and communicate does not stop. We still need to be able to find potable water, to call an ambulance, to administer medical treatment, to buy, preserve, and prepare food, to perform our jobs to the best of our ability, to heat our homes, to entertain our young children to keep them out of trouble, and to let our loved ones know that we are still alive. (Speaking of that last item, it's appalling how many kids now fail to memorize any telephone number of address other than their own. THAT trend has to be stopped.)
Even if the power goes down for a day, it can cause problems for unprepared people. If you rely on wireless broadband for all your news (including tornado warnings), then what happens when a power outage knocks out your router, or a storm that is 5 miles away takes out the cell tower? If every battery-powered device you own is an Apple, you're going to be out of luck, because they don't include radio receivers.
I saw this scenario in action just last week: I was in a hotel that lost power during a storm cycle in below-freezing temperatures, and you should have SEEN the panic among the majority of the guests, because almost no one, including the staff, had access to a regular battery-powered radio (I wasn't one of them, as it happens; I did have a radio easily to hand, but it did not have speakers.) It took 3 hours to get the hotel's generator running, and had there been a tornado in the area that might have been just too late. (Note that the hotel did HAVE a generator, however.) Lots of people were going out to sit in their cars just to get warm and try to get some news, but that wouldn't have lasted long either, because in a city-wide power outage most of the gas pumps were not functional. I had at least 30 people ask me to tell them what time it was, because I was -- wait for it -- wearing a watch.
