None of this is a surprise. Tons of "green screen" applications are in use today. I use a TN3270 session daily at work along with many other IBM CICS applications that were, ahem, "upgraded" to a web interface. A well designed 3270 or 5250 terminal application is WAY easier to work when than a stupid slow web interface.
I swear that all these "upgrades" meant to replace all those "primitive" POS systems from the 80s and 90s with slick 'n click systems that do everything have only made things worse.
They are slow, cumbersome, and people can't figure out how to use them because the UI was designed by idiots who think having everything controlled by a single, 1920x1080 button with no visual cues and
no explanation is fine and good.
To be sure, the old systems had a learning curve too, and they are genuinely slower and less secure, but once learned, they seemed quite fast and efficient for most ordinary things.
Crazy thing was, said ex-employer was relying on that AS/400, maybe beyond 2010? Only switched to something more modern when HIPAA demanded it.
That's absurd. The old AS/4000 setup, ironically, is probably far more secure than anything modern!
My dentist has to keep digital files stored in a very special, super secure server
locked in a concrete vault and only accessible to a specially licensed person. As recently as 5 years ago, no problem! Keep the files where you like, so long as you follow security best practices. But nowadays you'd think a persons' tooth x-ray is equivalent to some top secret government document!
If I were ever in any kind of work where that level of security was mandated by law, regardless of whether or not it actually makes any sense, I'd rather not bother with computerization at all and just go back to paper.
