Are you certain it wasn't signed, "Mr. Dinosaur"?
Actually, it reminds me of letters I read in the paper back in 1909 when the Model T Ford was introduced. It was a call to arms to stop those "newfangled" horseless carriages. Horse owners all over the place were having a fit. There were only 106 million people in 1910 and the country did not have paved roads or gas stations on every corner and in the following 18 years Ford alone sold 15 million cars.
Maybe not in our lifetime, but someday in the not-to-distant future, there will be no such thing as an internal combustion engine in use for transportation, just like there are no horses and buggies being used for transportation today. He can protest all he wants, but he might as well go to the shores of the Pacific Ocean and protest against the waves from crashing on the beach.
It is very interesting but exactly 100 years ago a new form of transportation was introduced and it changed the world and now 100 years later, another new form of transportation is hitting the market and it too will change the world.
