Technology and knowledge move forward and we must cast off older "given's". What about all of those premium Composite, Component, and early HDMI cables that we installed as a hedge against future developments. Plus all of those TV's we installed that don't have eARC ports. We are no better than the medical professionals who are still learning about the ever evolving COVID landscape.

Obviously I'm not suggesting that we quarantine people over interconnect compatibility, but we accept the idea that electronics technology evolves, and this is good, while rejecting the idea that medical knowledge evolves too.

One aspect of the dilemma is that an unfortunately large population segment is eager to accept the claims of snake oil salesmen, rather than rational information. (Witness the $2500 audiophile grade network switch we are discussing elsewhere)
