TL;DR: It is found that most urban indicators scale linearly with city size, regardless of the definition of the urban boundaries, however, when nonlinear correlations are present, the exponent fluctuates considerably.

TL;DR: This simulation shows that uncoordinated drivers possibly waste a considerable amount of their travel time, and suggests that simply blocking certain streets can partially improve the traffic conditions.

TL;DR: The barriers that inhibit scientists from measuring the effects of AI and automation on the future of work are discussed and a decision framework that focuses on resilience to unexpected scenarios in addition to general equilibrium behavior is recommended.

TL;DR: It is found that the combinatorial inventive process exhibits an invariant rate of ‘exploitation’ (refinements of existing combinations of technologies) and “exploration” (the development of new technological combinations) and the generation of novel technological combinations engenders a practically infinite space of technological configurations.

TL;DR: A self-consistent statistical framework is built that characterizes the joint probability distributions of urban indicators and city population sizes across an urban system and shows that scaling laws emerge as expectation values of these conditional statistics.
