Simplify Leo Szilard was instrumental to the development of atomic bomb technology. However, at the end of his career, he also spent much of his time lobbying to ensure that his legacy was put to peaceful usage. There is a lesson here for those of us who wish to be "social marketing experts." We must devote our energies to building the best technology that we can. But we also owe it to ourselves and our communities to see that it is used for what a broad consensus of society agrees is its own social good. Would you please simplify the last sentence? (what does the second "it" refer to in the last sentence?) Thanks a lot in advance
