Arthur C. Clarke, the famous science fiction writer, developed three "laws" of prediction, known as Clarke's Three Laws. The third of those laws is that any sufficiently advanced technology is indistinguishable from magic. In other words, if you were to find yourself in Biblical times with a computer, to the people native to that time, the fact that the computer works will seem as magic to them.
Apparently, this law holds today as well. From YNet:
A recently released album containing songs performed by legendary cantors has been causing turmoil among the ultra-Orthodox community due to the simple fact that the performers are all dead.
Apparently, the concept of manipulating audio recordings is too advanced for some people, because they
flooded the company with questions and complaints: "How is it that the cantor knows to wait for the orchestra? There must be some sort of spell here – is this séance? Does the Halacha allow tampering with the voices of the dead?"
I just don't know what to say... I'm at a complete loss for words.
