Token Ring was still popular only 20 years ago. I haven’t seen it used in over a decade. MFM hard drives were the standard until about 25 years ago, and it’s been hard to find a computer that can interface with one for over 15 years. VLB was THE interface for high-speed graphics cards, haven’t seen a computer with a VLB bus in over 15 years.
How long do they expect these things to remain usable? Bluetooth? How long is that going to be around?
People have posed the same question about digital pictures. No more images from the past found on glass negatives.
