Different religions have strikingly different views of history; but the emergence of modern technology offers promises of salvation that can draw equally on Christian views of time in the US and Hindu views of time in India. For centuries, Christian theologians incorporated technological progress into their linear vision of history, which will end with an eschatological conflict and the rise of the New Jerusalem. In the US today, techno-enthusiasts have adopted the claim that we are fast approaching the end of the world as we know it, though the salvation they expect no longer references Christianity. A ‘Singularity’ will occur, they say, leading to the transformation of biological life into an eternal new world of machine intelligence. In India, however, history is cyclical and the end of the world has long been expected to be a return to the first age. Although presently mired in the misery of the kali yuga, we should anticipate an end to this period and a return to the glorious satya yuga. Based upon popular Indian understandings of science and technology, we should expect that both will be crucial to this process. Interviews and observations made in the US and in India reveal how technological progress is now the critical component in cultural expectations about the end of the world and the emergence of a new world to come.
