The rant in the post has some merit to it, but the thing it sort of misses is also the reason not to use VM. It works just fine. It hasn't been updated in 20 years because it still works. It does what it says on the box. Why put it in a VM? What would you gain from it? If you need Internet just grab a laptop and have it sit next to the main computer. That way users have a much smaller chance to break something vital. Pretty much all the control computers are air gapped anyway. No updates or anything to break things you reeeeally don't want to break.
The only case I've seen VMs being used is if the old computer breakes and you can't really find something that's compatible with old-as-fuck software om bare metal. I work in a cleanroom and we got sooo many systems that are windows 95 or older (DOS anyone?). Electron microscope, etching systems, probe stations
The merit is security, as you can manage what goes into the VM as oppose to having the hardware where people can just plugin a flash drive or network cable.
Then there is also the improvement to not needing to maintain the old hardware, and having a backup of the entire system that you can just copy to a different system and have everything running again.
Sure I can see it being a security feature, random USBs are not a good thing, but I feel like it is quite minor with an air gapped system, no?
The backup is a good point. Though from this I started wondering how difficult it is to get the VM to communicate with old hardware. Like, the hardware might use some random method of actually communicating with the computer, ans getting that through to the VM might be problematic? I have no clue, just spitballing here.
