. . . lest anyone think I am arguing against cable break-in, I am not 😊
It’s just one of those kinds of questions (which is how I think of it instead of an argument) I find fascinating.
Lately I’ve begun studying quantum cryptography which has also drawn me into reading about quantum entanglement. Won’t go completely off on a tangent here but entanglement is mind-blowing and defies so much we think we understand and believe about how things are and work. The concept has existed since around 1927. Einstein called it “spooky action at a distance” and did not see how it could be real but also said he did not want to “know he was right” but “IF he was right”. The tech to test in his day was limited but current experiments are strongly suggesting quantum entanglement is real.
Maybe cable break-in is a “spooky” thing that exists and we haven’t yet used a “lab” approach that detects and explains it.
