Concluding Remarks

Abstract

The mood at this conference is summarized in David Hughes' comment, ``this decade will be amazing.'' We've just had a pretty good ten years of advances in cosmology and extragalactic astronomy; why should we expect a repeat, another decade of comparable or even greater progress? The obvious answer is that there still are many more questions than answers in cosmology, and a considerable number of the questions will be addressed by research programs planned and in progress: we certainly are going to learn new things. But beyond that is the fact that there is no practical limit to the hierarchy of interesting topics to explore in this subject. I organize my comments on the state of research, and the prospects for substantial new developments in the coming decade of multi-wavelength cosmology, around the concept of social constructions.
