Companies probably will.
We're still running a CNC mill powered by DOS. It's in great mechanical shape, the legacy software makes a specific product that we have a good market for, it's obviously a completely standalone unit with no security concerns.
It's kind of ridiculous actually, we've upgraded the mainboards and processors from 486 to Celeron, SSDs with SATA-> IDE adaptors etc but the software and the hardware drivers run on DOS and there's no practical upgrade path. We will run her until she can't make tooling anymore
I've been collecting any and all documentation pertaining to this machine and in many cases the guys I've ended up talking to are the only ones who haven't retired. Fortunately everyone so far has been happy to give me a huge data dump of everything on their drives, knowing that nobody on their end will be available to support it in a few years.
What really scares me is not the software but the aging protocols that talk to obsolete hardware. Lose one of the old AC servomotor drives and good luck finding a way to integrate a modern unit. Easy enough to mate something up to the motor and feedback, not so easy to get it to speak whatever specific flavour of SERCOS was used on the machine. At least it isn't a proprietary protocol... I'm still hoping I never have to do it.
Sigh. You said it yourself, somewhere. Not everywhere.
It's important because it means there will still be a lot of PCs going to a landfill. That's how the duscussion started.
Hahahahahaha.......breathes..,.. hahahahah
But in all seriousness, they %100 will not. There are still companies that have winxp machines and servers on 2000/2003.
There is an entire sector of the secops industry built on protecting these machines.
Not 100%, but most big businesses will.
