I agree that the problem isn't that these machines are from the 60s. They may have even been cutting edge then. Indeed, the problem is that the user of the machine faced a choice between 3 possibilities: replacing the machine as expertise in the old tech dwindled; building and maintaining that expertise over the course of decades; or doing neither, and letting the equipment inevitably lapse into its inevitable disrepair; and they chose the latter. Change is constant, which is good, because there is no progress without it. The only choice we have as individuals is how, and how well, we adapt to it.
