Transparency, openness, and reproducibility are readily recognized as vital features of science (1, 2). When asked, most scientists embrace these features as disciplinary norms and values (3). Therefore, one might expect that these valued features would be routine in daily practice. Yet, a growing body of evidence suggests that this is not the case (4–6). A likely culprit for this disconnect is an academic reward system that does not sufficiently incentivize open practices (7).

Editors provide an introduction to Science's special section on the Rise of the Machines. Drivers of progress of machine learning, its recent advances, and future challenges are reviewed. Applications such as machine translation, spoken dialogue systems, and sentiment analysis of social media are reviewed. Artificial agents behave rationally, free from the biases and heuristics that computationally limited humans exhibit.
