A book is more like the score of a piece of music than it is like a painting. No great musician confuses a symphony with the printed sheets of music. Arturo Toscanini reveres Brahms, but Toscanini's score of the G minor Symphony is so thoroughly marked up that no one but the maestro himself can read it. The reason why a great conductor makes notations on his musical scores -- marks them up again and again each time he returns to study them--is the reason why you should mark your books.

the physical act of writing, with your own hand, brings words and sentences more sharply before your mind and preserves them better in your memory. To set down your reaction to important words and sentences you have read, and the questions they have raised in your mind, is to preserve those reactions and sharpen those questions.

that is exactly what reading a book should be: a conversation between you and the author. Presumably he knows more about the subject than you do; naturally, you'll have the proper humility as you approach him. But don't let anybody tell you that a reader is supposed to be solely on the receiving end. Understanding is a two-way operation; learning doesn't consist in being an empty receptacle. The learner has to question himself and question the teacher. He even has to argue with the teacher, once he understands what the teacher is saying. And marking a book is literally an expression of differences, or agreements of opinion, with the author

rather than making us smarter, mobile devices reduce our cognitive ability in measurable ways

“There’s lots of evidence showing that the information you learn on a digital device, doesn’t get retained very well and isn’t transferred across to the real world,”

“You’re also quickly conditioned to attend to lots of attention-grabbing signals, beeps and buzzes, so you jump from one task to the other and you don’t concentrate.”

scholars are watching Carpenter’s case closely because it may require the supreme court to address the scope and continuing relevance of the “third-party-records doctrine”, a judicially developed rule that has sometimes been understood to mean that a person surrenders her constitutional privacy interest in information that she turns over to a third party. The government contends that Carpenter lacks a constitutionally protected privacy interest in his location data because his cellphone was continually sharing that data with his cellphone provider.

Privacy advocates are rightly alarmed by this argument. Much of the digital technology all of us rely on today requires us to share information passively with third parties. Visiting a website, sending an email, buying a book online – all of these things require sharing sensitive data with internet service providers, merchants, banks and others. If this kind of commonplace and unavoidable information-sharing is sufficient to extinguish constitutional privacy rights, the digital-age fourth amendment will soon be a dead letter.

“Awareness that the government may be watching chills associational and expressive freedoms,” Chief Justice John Roberts wrote. Left unchecked, he warned, new forms of surveillance could “alter the relationship between citizen and government in a way that is inimical to democratic society”.

some students ask why they should be required to convince anyone of anything. "After all," they say, "we are all entitled to our opinions, so all we should have to do is express them clearly. Here's my opinion. Take it or leave it." This point of view both misunderstands the nature of argument and ignores its greatest value

In an Age of Information, what most professionals do is research, think, and make arguments. (And part of the value of doing your own thinking and writing is that it makes you much better at evaluating the thinking and writing of others.)

Words such as "show how" and "explain" and "illustrate" do not ask you to summarize a reading. They ask you to show how the reading is put together, how it works

for a great many people, the permanent memory bank of the Web increasingly means there are no second chances — no opportunities to escape a scarlet letter in your digital past. Now the worst thing you’ve done is often the first thing everyone knows about you.

a collective identity crisis. For most of human history, the idea of reinventing yourself or freely shaping your identity — of presenting different selves in different contexts (at home, at work, at play) — was hard to fathom, because people’s identities were fixed by their roles in a rigid social hierarchy. With little geographic or social mobility, you were defined not as an individual but by your village, your class, your job or your guild. But that started to change in the late Middle Ages and the Renaissance, with a growing individualism that came to redefine human identity. As people perceived themselves increasingly as individuals, their status became a function not of inherited categories but of their own efforts and achievements. This new conception of malleable and fluid identity found its fullest and purest expression in the American ideal of the self-made man, a term popularized by Henry Clay in 1832.

the dawning of the Internet age promised to resurrect the ideal of what the psychiatrist Robert Jay Lifton has called the “protean self.” If you couldn’t flee to Texas, you could always seek out a new chat room and create a new screen name. For some technology enthusiasts, the Web was supposed to be the second flowering of the open frontier, and the ability to segment our identities with an endless supply of pseudonyms, avatars and categories of friendship was supposed to let people present different sides of their personalities in different contexts. What seemed within our grasp was a power that only Proteus possessed: namely, perfect control over our shifting identities. But the hope that we could carefully control how others view us in different contexts has proved to be another myth. As social-networking sites expanded, it was no longer quite so easy to have segmented identities: now that so many people use a single platform to post constant status updates and photos about their private and public activities, the idea of a home self, a work self, a family self and a high-school-friends self has become increasingly untenable. In fact, the attempt to maintain different selves often arouses suspicion.

experts predicted networked artificial intelligence will amplify human effectiveness but also threaten human autonomy, agency and capabilities

most experts, regardless of whether they are optimistic or not, expressed concerns about the long-term impact of these new tools on the essential elements of being human. All respondents in this non-scientific canvassing were asked to elaborate on why they felt AI would leave people better off or not. Many shared deep worries, and many also suggested pathways toward solutions. The main themes they sounded about threats and remedies are outlined in the accompanying table.

CONCERNS Human agency: Individuals are  experiencing a loss of control over their lives Decision-making on key aspects of digital life is automatically ceded to code-driven, "black box" tools. People lack input and do not learn the context about how the tools work. They sacrifice independence, privacy and power over choice; they have no control over these processes. This effect will deepen as automated systems become more prevalent and complex. Data abuse: Data use and surveillance in complex systems is designed for profit or for exercising power Most AI tools are and will be in the hands of companies striving for profits or governments striving for power. Values and ethics are often not baked into the digital systems making people's decisions for them. These systems are globally networked and not easy to regulate or rein in. Job loss: The AI takeover of jobs will widen economic divides, leading to social upheaval The efficiencies and other economic advantages of code-based machine intelligence will continue to disrupt all aspects of human work. While some expect new jobs will emerge, others worry about massive job losses, widening economic divides and social upheavals, including populist uprisings. Dependence lock-in: Reduction of individuals’ cognitive, social and survival skills Many see AI as augmenting human capacities but some predict the opposite - that people's deepening dependence on machine-driven networks will erode their abilities to think for themselves, take action independent of automated systems and interact effectively with others. Mayhem: Autonomous weapons, cybercrime and weaponized information Some predict further erosion of traditional sociopolitical structures and the possibility of great loss of lives due to accelerated growth of autonomous military applications and the use of weaponized information, lies and propaganda to dangerously destabilize human groups. Some also fear cybercriminals' reach into economic systems.

Ballard was a brilliant futurist and his dystopian novels and short stories anticipated the 80s cyberpunk of William Gibson, exploring with a twisted sense of humor what Jean Lyotard famously dubbed in 1979 The Postmodern Condition: a state of ideological, scientific, personal, and social disintegration under the reign of a technocratic, hypercapitalist, “computerized society.” Ballard had his own term for it: “media landscape,” and his dark visions of the future often correspond to the virtual world we inhabit today.

Ballard made several disturbingly accurate predictions in interviews he gave over the decades (collected in a book titled Extreme Metaphors)

he gave an interview to I-D magazine in which he predicted the internet as “invisible streams of data pulsing down lines to produce an invisible loom of world commerce and information.” This may not seem especially prescient (see, for example, E.M. Forster’s 1909 “The Machine Stops” for a chilling futuristic scenario much further ahead of its time). But Ballard went on to describe in detail the rise of the Youtube celebrity: Every home will be transformed into its own TV studio. We'll all be simultaneously actor, director and screenwriter in our own soap opera. People will start screening themselves. They will become their own TV programmes.

The idea would be that not only do you have a multigenerational project of building a new world, but obviously the human civilization occupying it would also be new. And culturally and politically, it would be an achievement that would have no reason to stick with old forms from the history of Earth. It’s a multigenerational project, somewhat like building these cathedrals in Europe where no generation expects to end the job. By the time the job is near completion, the civilization operating it will be different to the one that began the project.

what the Mars scenario gave me – and gives all of humanity – is the idea that the physical substrate of the planet itself is also a part of the project, and it’s something that we are strong enough to influence. Not create, not completely control, not completely engineer because it’s too big and we don´t have that much ability to manipulate the large systems involved, nor the amount of power involved. But we do have enough to mess things up and we do have enough to finesse the system.This, I think, was a precursor to the idea of the Anthropocene. The Anthropocene is precisely the geological moment when humanity becomes a geological force, and it’s a science-fiction exercise to say that 50 million years from now, humanity’s descendants, or some other alien civilization, will be able to look at Earth and say: “This is when humanity began to impact things as much as volcanos or earthquakes.” So it’s a sci-fi story being told in contemporary culture as one way to define what we are doing now. So, that was what my Mars project was doing, and now we are in the Anthropocene as a mental space.

if humanity’s impact on the Earth is mostly negative in ecological terms, if you mark humanity’s impact as being so significant that we have produced a new geological age, then we have to think differently in our attitudes towards what we are doing with our biophysical substrate. And one of the things I think the Anthropocene brings up is that the Earth is our body, and we can finesse it, we can impact it, we can make ourselves sick.

The Information World War has already been going on for several years. We called the opening skirmishes “media manipulation” and “hoaxes”, assuming that we were dealing with ideological pranksters doing it for the lulz (and that lulz were harmless). In reality, the combatants are professional, state-employed cyberwarriors and seasoned amateur guerrillas pursuing very well-defined objectives with military precision and specialized tools. Each type of combatant brings a different mental model to the conflict, but uses the same set of tools.

There are also small but highly-skilled cadres of ideologically-motivated shitposters whose skill at information warfare is matched only by their fundamental incomprehension of the real damage they’re unleashing for lulz. A subset of these are conspiratorial — committed truthers who were previously limited to chatter on obscure message boards until social platform scaffolding and inadvertently-sociopathic algorithms facilitated their evolution into leaderless cults able to spread a gospel with ease.

There’s very little incentive not to try everything: this is a revolution that is being A/B tested.

As the evening progressed, more and more questions concerning justice and ethics occurred to the physicists: Are atomic weapons inherently inhumane, and should they never be used? If the Germans had come to possess such weapons, what would be the world’s fate? What constitutes real patriotism in Nazi Germany—working for the regime’s success, or its defeat? The scientists expressed surprise and bafflement at their colleagues’ opinions, and their own views sometimes evolved from one moment to the next. The scattered, changing opinions captured in the Farm Hall transcripts highlight that, in their five years on the Nazi nuclear program, the German physicists had likely failed to wrestle meaningfully with these critical questions.

looking back at the Uranium Club serves to remind us scientists of how easy it is to focus on technical matters and avoid considering moral ones. This is especially true when the moral issues are perplexing, when any negative impacts seem distant, and when the science is exciting.

engineers who develop tracking or facial-recognition systems may be creating tools that can be purchased by repressive regimes intent on spying on and suppressing dissent. Accordingly, those researchers have a certain obligation to consider their role and the impact of their work.

Levels of trust in news on social media, search engines, and messaging apps is consistently lower than audience trust in information in the news media more generally.

Many of the same people who lack trust in news encountered via digital media companies – who tend to be older, less educated, and less politically interested – also express less trust in the news regardless of whether found on platforms or through more traditional offline modes.

Many of the most common reasons people say they use platforms have little to do with news.

After Iranian lawmakers suggested last year that face recognition should be used to police hijab law, the head of an Iranian government agency that enforces morality law said in a September interview that the technology would be used “to identify inappropriate and unusual movements,” including “failure to observe hijab laws.” Individuals could be identified by checking faces against a national identity database to levy fines and make arrests, he said.

Iran’s government has monitored social media to identify opponents of the regime for years, Grothe says, but if government claims about the use of face recognition are true, it’s the first instance she knows of a government using the technology to enforce gender-related dress law.

Mahsa Alimardani, who researches freedom of expression in Iran at the University of Oxford, has recently heard reports of women in Iran receiving citations in the mail for hijab law violations despite not having had an interaction with a law enforcement officer. Iran’s government has spent years building a digital surveillance apparatus, Alimardani says. The country’s national identity database, built in 2015, includes biometric data like face scans and is used for national ID cards and to identify people considered dissidents by authorities.
