We revisit the problem of constructing an elusive scaling theory of the strange-metal phase of the cuprates. By using the four robust experimentally established temperature dependences as the constitutive relations we then predict the scaling behaviors of a number of other observables, all those for which the reliable data are available being in agreement with experiment. Such predictions are also contrasted against the recent proposal inspired by the holographic approach, thus allowing one to critically assess the status of the latter.
