It's an interesting argument, as David remarks. Note - I don't believe
that Mahler does actually indicate for or against normality, simply
that it deals with concepts related to normality, and proves that the
digits are not IID. Normality is independent of that property, of course.

I worded my post deliberately, playing epsilontics; Mahler is (to
my mind) the strongest indication, where its strength is epsilon,
such that for any number delta greater than zero, epsilon<delta.
