  We elucidate a cancellation mechanism for the electric dipole moment of the
electron in the general two Higgs doublet model. The impressive improvement by
the ACME Collaboration in 2018 suggests the presence of a new electron Yukawa
coupling that brings in exquisite cancellations among dangerous diagrams,
broadening the solution space for electroweak baryogenesis driven by an extra
top Yukawa coupling. The cancellation mechanism calls for the new Yukawa
couplings to have hierarchical structures that echo the observed pattern of the
Standard Model Yukawa couplings.
