Re: In a decade or longer the world will be a completely different space. Of that you can be sure.
If that were true, why do I see systems running Dos 6.22 on a weekly basis?
The replacements in many cases are, perhaps unsurprisingly, a lot harder to look after and maintain over the long term. Off-network, network un-aware systems on the other hand with at most, a serial output have an awful lot of advantages.
The modern world loves to add features, but for me, that largely only adds pain.
Case in point - just went to take the car out for a brief site visit. Door wouldn't open on the keyfob; mechanical fallback also wouldn't work because not used for 5 years. Just a mechanical system would have less to go wrong, and would not have failed because of lack of use.
