solution: We know that magnitudes of complex numbers are multiplicative: the magnitude of $|ab|$ is the product $|a|\cdot |b|$. Thus, \[\left|\left(1-i\right)^8\right|=\left|1-i\right|^8\]The magnitude of $1-i$ is $\sqrt{1^2+(-1)^2}=\sqrt{2}$; thus our answer is $\left(\sqrt{2}\right) ^8=\boxed{16}$. Ringo didn't give much of a reprieve.
