Yes, Hannes Alfven may be gone, but he is not forgotten.
Even so, with virtually every new observation, gravity and fusion are losing their power as explanatory concepts among NASA scientists. We cannot expect an immediate and wholesale revolution in science, but we can definitely appreciate that magnetic fields, jets, filaments and all the other concepts of plasma cosmology are gaining ground, however haltingly. Our ship finally comes in when we can quantify the charge density of celestial objects, first of all Sol. Until then, we must be content with small steps and little victories.
