In particular, the author laments the high cost of scans:
> Here in Switzerland I am looking at a cost of around 30.- CHF a frame minimum if I get a third party to scan them for me.
And worries that you have to have something like the 2007 iMac to run it:
> So you need a dedicated old rig to run the proprietary software to drive the scanner.
But doesn't seem to quite connect 2 and 2 together: Those third party shops all have ancient dedicated rigs that they bought a decade or two ago. The use of that equipment is what your $30 per scan is buying! There are label printers and laser markers and time clocks and press brakes and CNCs and inventory management systems at shops all over the world, running some PLC RTOS from the 90s, or DOS or Windows 98 with PXI cards or printer parallel ports or even completely proprietary logic boards, that are decades old and you can't get parts or service or updates for them.
It's ubiquitous in any less profitable industries that aren't on the cutting edge.
It's hard to maintain and gradually update this equipment. I fear it's going to get harder as IIoT services die off and engineered lifetimes shrink. It's hard to debug a machine built before the Internet, with coffee-stained schematics and only enough IDE hard drive space for 8-character variable names, but I worry it will be harder still to debug a machine built well after the Internet with ubiquitous documentation available only behind a login to a server that's no longer online and enough hard drive space for gigabytes of third-party libraries...
