Fifty years have just passed since the first discovery of the extra-solarX-ray sources by Giacconi and his team which we know today to be some stellarmass black holes. By 1973, not only a catalog of these enigmatic objects weremade, and their spectra were obtained. Today, forty years have passed since therevolutionary idea of the thin, axisymmetric, Keplerian, disk model by Shakuraand Sunyaev was published. Yet, the complete predictability of their radiativeproperties remains as illusive as ever. The only available and self-consistentsolution to date is the generalized viscous transonic flow solutions where bothheating and cooling effects are included. I demonstrate that the latest`Avatar' of the accretion/outflow picture, the Generalized Two ComponentAdvective Flow (GTCAF), is capable of explaining almost all the black holeobservational results, when the results of the time dependent simulation ofviscous and radiative processes are also taken into consideration. I alsodiscuss the problems with predictability and argue that understandingcompanion's behaviour in terms of its habit of mass loss, ellipticity of itsorbit, magnetic properties, etc. is extremely important for the prediction ofemission properties of the accretion flow.
