"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

"America is in the very early stages of a big pedagogical experiment based on old ideas given new life by digital technology and the techies' money. There isn't enough evidence yet to conclude that this blend of technology and personalised learning serves pupils better than the status quo, but the revolution is gathering pace. It could, Rose acknowledges, "go horribly, horribly wrong". If it does, a lot of children's lives will have been damaged; but then it is hardly as though the existing system is releasing the full potential of America's young people. For Rose, giving children more control over what they learn and how they learn it is central to achieving that. Ultimately, he says, "you should have a right to know who you are.""

The empire doesn't care who is president | The Outline - 0 views

"The trouble with empires is that so much depends upon their emperors, and the trouble for emperors is how little they matter to their empires. No Caesar could end Rome by accident, no matter how myopic or incompetent they could be. Not the madman Caligula, not the idiot Commodus, not the vainglorious Maximinus Thrax - the border might wax or wane, but it made no difference really. Even Caracella, who sacked his own city of Alexandria for staging a funny play at his expense, couldn't ruin the whole empire. The empire just stabbed him in the back and carried on."
The implications of silent transmission for the control of COVID-19 outbreaks | PNAS - 0 views
-
Since the emergence of coronavirus disease 2019 (COVID-19), unprecedented movement restrictions and social distancing measures have been implemented worldwide. The socioeconomic repercussions have fueled calls to lift these measures. In the absence of population-wide restrictions, isolation of infected individuals is key to curtailing transmission. However, the effectiveness of symptom-based isolation in preventing a resurgence depends on the extent of presymptomatic and asymptomatic transmission. We evaluate the contribution of presymptomatic and asymptomatic transmission based on recent individual-level data regarding infectiousness prior to symptom onset and the asymptomatic proportion among all infections. We found that the majority of incidences may be attributable to silent transmission from a combination of the presymptomatic stage and asymptomatic infections. Consequently, even if all symptomatic cases are isolated, a vast outbreak may nonetheless unfold. We further quantified the effect of isolating silent infections in addition to symptomatic cases, finding that over one-third of silent infections must be isolated to suppress a future outbreak below 1% of the population. Our results indicate that symptom-based isolation must be supplemented by rapid contact tracing and testing that identifies asymptomatic and presymptomatic cases, in order to safely lift current restrictions and minimize the risk of resurgence.

Antarctic iceberg melt could hold the key to the activation of a series of mechanisms that cause the Earth to suffer prolonged periods of global cooling, according to Francisco J. Jiménez-Espejo, a researcher at the Andalusian Earth Sciences Institute (CSIC-UGR), whose discoveries were recently published in Nature.
An assault to the skies: the municipalist movement's affair with Podemos | openDemocracy - 0 views
-
Municipalism is nothing other than thousands of neighbours coming together in a joint effort to build a new model for their city. In the summer of 2014 a set of initiatives necessary for staging a so-called institutional assault were already appearing in several Spanish cities: the municipalist movements. These departed from existing common grounds in their desire to overcome the two-party system, end with corruption, and democratise the local councils.
Modeling the global economic impact of AI | McKinsey - 0 views
-
The role of artificial intelligence (AI) tools and techniques in business and the global economy is a hot topic. This is not surprising given that AI might usher in radical—arguably unprecedented—changes in the way people live and work. The AI revolution is not in its infancy, but most of its economic impact is yet to come.
-
New research from the McKinsey Global Institute attempts to simulate the impact of AI on the world economy. First, it builds on an understanding of the behavior of companies and the dynamics of various sectors to develop a bottom-up view of how to adopt and absorb AI technologies. Second, it takes into account the likely disruptions that countries, companies, and workers are likely to experience as they transition to AI. There will very probably be costs during this transition period, and they need to be factored into any estimate. The analysis examines how economic gains and losses are likely to be distributed among firms, employees, and countries and how this distribution could potentially hamper the capture of AI benefits. Third, the research examines the dynamics of AI for a wide range of countries—clustered into groups with similar characteristics—with the aim of giving a more global view.
-
The analysis should be seen as a guide to the potential economic impact of AI based on the best knowledge available at this stage. Among the major findings are the following: There is large potential for AI to contribute to global economic activity A key challenge is that adoption of AI could widen gaps among countries, companies, and workers

In his video, He presented himself as a willing martyr to some higher cause. “I understand my work should be controversial, but families need this technology, and I am willing to take the criticism,” he said.
Jeff Sessions is shamefully undermining WEB Du Bois's legacy | Marc Mauer - 0 views
-
Since 2002, the US Department of Justice’s WEB Du Bois program has sponsored research fellowships on issues of race and criminal justice. During Republican and Democratic administrations, a diverse group of academics have carried the spirit of the noted sociologist and civil rights leader to the race challenges of the 21st century. Given the racial disparity endemic at every stage of the justice system the DoJ’s investigation of these issues has been praiseworthy. But with Jeff Sessions as attorney general exploring the roots of this injustice may now be compromised. In the recently released solicitation for the Du Bois fellowships the DoJ invited scholars to engage in research on five issues arising out of the “tough on crime” era that would make a student of the Du Bois legacy shudder. Whereas Du Bois is widely known for promoting the idea that “the problem of the 20th century is the problem of the color line”, the DoJ solicitation displays no interest in such high-profile issues as police killings of unarmed black men or the impact of mass incarceration on the African American community. Instead, “protecting police officers” is the only area of law enforcement prioritized by the DoJ. Another research priority, “enhancing immigration enforcement”, coming at a moment when barely disguised racist imagery accompanies those policies, seems particularly jarring when upheld in the name of a civil rights legend. The DoJ approach to research is unfortunately consistent with the misconstrued “law and order” agenda that Jeff Sessions has brought to his leadership. Within a month of taking office Sessions had rescinded the Obama-era decision to phase out federal contracting with private prisons. That initiative had been based in part on an inspector general’s finding that such prisons had higher levels of assault and safety concerns than public prisons.
