This Will Change Everything is a compilation of responses to the 2009 Edge question, “What game-changing scientific ideas and developments do you live to see?” As one might expect, the responses more or less converged on a few common themes: climate change, biological engineering, nuclear war, ubiquitous computing, etc. But there were also a few more peripheral predictions: the discovery of a proof for the Riemann Hypothesis, the commercialisation of neurocosmetics, the evolution of masculine subjectivity, and the perfection of lie detectors, just to name a few.
