"With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

"I have come to the conclusion that capitalism is successful primarily because it can impose the majority of the costs associated with its economic activities on outside parties and on the environment. In other words, capitalists make profits because their costs are externalized and born by others. In the US, society and the environment have to pick up the tab produced by capitalist activity. In the past when critics raised the question about external costs, that is, costs that are external to the company although produced by the company's activities, economists answered that it was not really a problem, because those harmed by the activity could be compensated for the damages that they suffered. This statement was intended to reinforce the claim that capitalism served the general welfare. However, the extremely primitive nature of American property rights meant that rarely would those suffering harm be compensated. The apologists for capitalism saved the system in the abstract, but not in reality."

"As AI systems become more general and more useful in the real world, ensuring they behave safely will become even more important. To date, the majority of technical AI safety research has focused on developing a theoretical understanding about the nature and causes of unsafe behaviour. Our new paper builds on a recent shift towards empirical testing (see Concrete Problems in AI Safety) and introduces a selection of simple reinforcement learning environments designed specifically to measure 'safe behaviours'."

new study uses satellite data over the Southern Hemisphere to understand global cloud composition during the industrial revolution. This research tackles one of the largest uncertainties in today's climate models-the long-term effect of tiny atmospheric particles on climate change.

To overcome - once and for all - the false separation between nature and culture requires us to acknowledge that learning from human ingenuity and long-term adaptations to particular environments is also learning from nature. Among indigenous peoples there is a long tradition of solving human problems by learning from other species and from the wider natural processes in which we participate.
