You would be amazed, and terrified, on how many legacy systems run things. And, the stories that I can tell of some people’s upcoming fear of when Windows 95/98 systems are no longer usable for any number of reasons. How many pieces of medical equipment run on embedded Windows-based OS systems based on Windows 95. Oh, how many of those self-checkout systems run on Windows OS systems…
This would actually make for an interesting story. I know there are people that are pulling down six figure consulting contracts because they know COBOL. Because most large industrial systems, most State and Federal systems, still use COBOL. And, the cost to handle the switchover is going to be very, very painful when it happens.
It’ll be fun when a lot of these things have to be fixed. Just make sure to keep paper backups of everything.
