Yep, the generational thing becomes more acute with each passing day, duhn't it? <g>
I remember my mentors telling me the same thing, about myself, a half-century ago, and I'm sure they were told the same thing back in their day.
I've given this subject some thought lately, recalling a time about eighteen years ago when Power over Ethernet (phantom power provisioning) was first discussed in the trades, and then again a few years later when it was ratified by the IEEE as an Ethernet standard.
Despite some vendors trying to take credit for devising the technology, power provisioning over the same physical media as that being used by bearer channels has been taking place ever since the 1830s, when tearly telegraphers used battery and ground over open wire transmission facilities to send Morse code over distances. And such as been true for virtually every generation of inside- and outside- line and equipment technologies (both Telco and Cable) since then. Earlier designs might have been called phantom powering, simplex power, line powering, to name a few.
While the foregoing may have been a bubble-bursting revelation to the apprentice of fifteen years ago, it's lost its punch today due to PoE's slowly becoming assimilated as part of today's woodwork, so to speak. Yet, it has become common to find references to PoE in the trades and the literature as a technology that was devised during the 21st Century.
