There’s not particularly good reason to stop doing it in that scenario either.
You have an offline technology stack in that elevator that has been doing the job correctly for 20 years. Why take on the expense and risk of changing things that aren’t currently broken?
It would be crazy if you are building new to resort to that stack, but for an established elevator, why bother?
Same for some old oscilloscopes at work. I’m not crazy about the choice but I can hardly suggest it would be practical to change it while the oscilloscopes still do their function.
I would say it’s a problem if the stack is online, but if it is self contained, the age of the software doesn’t make it a problem in and out itself.
I referenced both parts of your comment. First that things were good without any segue as to why you think this contributes.
Then to your assertion that we now have these and didn’t have then before due to lack of community, and I find that to be odd to say about a currently isolated incident that had nearly zero precedent.
