I have spoken briefly with Jerry Palmer about this. He has apparently already had some reassurance from some quarter that things are under control. However, PCs will also be affected. There is also the issue of every one of those favorite old software programs that we re running. Nor is this just a matter of what happens to our ability to pay our teachers and other vendors, and to get access to data on our hard drives.
Computer chips are everywhere.
If there is a glitch somewhere in the banking system, electric power grid, natural gas pumping stations, etc., etc., we will have a problem. Some people are taking all their money out of the bank, stockpiling food, etc. I am not of that camp. My guess is that things will be nowhere near as awful as the doomsayers predict. But no one can know, at this point.
