What the article says around this equation
with T 1 year in the 1965 paper’s implied rate and T 2 years in Moore’s own 1975 revision [ 1 , 2 ] . A model that halves its own rate parameter after a decade of data is not a law of nature; it is a working forecast that its author corrected in public once, using new evidence, at a named conference. That the popular shorthand later collapsed both versions into a single unchanging “law” says more about the appeal of a clean number than about what either paper actually claimed.
