We argue that the bipolaronic Bose-liquid is the only possible extensi
on of the BCS theory to the strong coupling regime. A large number of
experimental observations supports the bipolaronic charged 2e Bose-liq
uid as the ground state of high-T-c copper oxides. We discuss the poss
ibility of direct experiments.
