And the CIA's job is as much to spy on this world of established industrial capability as it is to hunt down laser-toting agents in the urban jungle of Beijing.
Don't ask me how I know. It took AGES to purge our ERP system of any reference to the Siemens item# which resulted in a floppy showing up.
On the other hand, it resulted in some business for both DHL and whoever still manufactures floppy drives nowadays - service engineers opening a package somewhere in the world, finding what kids today would assume was a 3d-printed 'save' icon - and order a drive, double haste...
If you dont need the extra capacity or speed that USB or optical offers you, don't upgrade. I mean this specifically for infrastructure-size projects where the "thing" / entity that is controlled costs multiple orders of magnitude more than the computer system controlling it. Say I have a hydro-electric dam, or any kind of power plant (not just nuke), or train switch controller, submarine, aircraft carrier, etc. Stuff that can't break. Its just cheaper and safer to keep using the same tech, keep replacing known-working parts, than it is to risk updating the system to "stay current", and risk a costly outage (or some kind of catastrophe, even if theres only a 10^-7 chance of it happening). I dont blame them one bit.
OTOH, the only way to actually preserve data is to keep rolling them forward to new physical media as the old ones die off (this is of course abstracted away in cloud solutions).
Any university has dozens of labs with 386s, or similar vintage, because the software they need to operate incredibly expensive equipment is abandonware.
In fact an IT guy I knew kept the best surviving examples of vintage computers in his closet for parts or to transfer data with.
