I don't think any network cabling you could have conceived of

Actually, 10Mb Ethernet over cat3 cable was introduced in 1990 and the
standard for cat5 cable was published in 1991 which will still work
today with 10Mb, 100Mb or 1Gb Ethernet, and I can't see much pressure
for 10Gb or 40Gb Ethernet in most businesses yet, let alone houses.
