In the spring of 1822 an employee in one of the world’s first offices – that of the East India Company in London – sat down to write a letter to a friend. If the man was excited to be working in a building that was revolutionary, or thrilled to be part of a novel institution which would transform the world in the centuries that followed, he showed little sign of it. “You don’t know how wearisome it is”, wrote Charles Lamb, “to breathe the air of four pent walls, without relief, day after day, all the golden hours of the day between ten and four.” His letter grew ever-less enthusiastic, as he wished for “a few years between the grave and the desk”. No matter, he concluded, “they are the same.”

The world that Lamb wrote from is now long gone. The infamous East India Company collapsed in ignominy in the 1850s. Its most famous legacy, British colonial rule in India, disintegrated a century later. But his letter resonates today, because, while other empires have fallen, the empire of the office has triumphed over modern professional life.

The dimensions of this empire are awesome. Its population runs into hundreds of millions, drawn from every nation on Earth. It dominates the skylines of our cities – their tallest buildings are no longer cathedrals or temples but multi-storey vats filled with workers. It delineates much of our lives. If you are a hardworking citizen of this empire you will spend more waking hours with the irritating colleague to your left whose spare shoes invade your footwell than with your husband or wife, lover or children.

Or rather you used to. This spring, almost overnight, the world’s offices emptied. In New York and Paris, in Madrid and Milan, they ready themselves for commuters who never come. Empty lifts slide up and down announcing floor numbers to empty vestibules; water coolers hum and gurgle, cooling water that no one will drink. For the moment, office life is over.

Even before coronavirus struck, the reign of the office had started to look a little shaky. A combination of rising rents, the digital revolution and increased demands for flexible working meant its population was slowly emigrating to different milieux. More than half of the Ameri­can workforce already worked remotely, at least some of the time. Across the world, home working had been rising steadily for a decade. Pundits predicted that it would increase further. No one imagined that a dramatic spike would come so soon.

It’s too early to say whether the office is done for. As with any sudden loss, many of us find our judgment blurred by conflicting emotions. Relief at freedom from the daily commute and pleasure at turning one’s back on what Philip Larkin called “the toad work” are tinged with regret and nostalgia, as we prepare for another shapeless day of WFH in jogging bottoms.

Humans need offices. Online encounters may be keeping us alive as social beings right now, but work-related video meetings are too often transactional, awkward and unappealing. After the initial joy of peering into each other’s houses on Zoom, we are confronted with people’s heads looming even closer than we see them across the desk at work, and we gaze in horror – half of it self-awareness that we, too, must look awful – at thinning hair and double chins. We become freakish specimens rather than people. No Skype chat can replicate what Heatherwick calls the “chemistry of the unexpected” that you get in person. Offices may not fill the pages of poetry anthologies but, says Kellaway, they “can be as moving as anywhere on Earth. Because what moves us is not sitting at our computer, it’s the relationship that we have with people.”

For all his grumbling, Charles Lamb believed something similar too. When Wordsworth seems to have grown a trifle too smug about the sublime joys of the natural world, Lamb snapped back. “I don’t much care if I never see a mountain in my life.” But he did care for the city and he certainly loved offices. All his complaints were, he wrote, mere “lovers’ quarrels”. Above all, he loved his desk. For it was that “dead timber of a desk that makes me live”

Must read article to understand AI in simple language. Today’s AI and machine learning is dependent on probabilistic correlations and not cause and effect learning. But “Correlations can often lead to insufficient or inaccurate conclusions. This point was clearly illustrated by an observational study on women’s health conducted in the 1990’s that concluded that Hormone Replacement Therapy (HRT) had a beneficial effect in mitigating heart disease. The same statistical view of the data also revealed a protective effect of HRT on homicide rates. When experts re-analyzed the data and adjusted for important confounding factors, they found that HRT actually had an adverse effect on heart disease and no effect on the homicide rate.”.

Three decades ago, a prime challenge in artificial-intelligence research was to program machines to associate a potential cause to a set of observable conditions. Pearl figured out how to do that using a scheme called Bayesian networks. Bayesian networks made it practical for machines to say that, given a patient who returned from Africa with a fever and body aches, the most likely explanation was malaria. In 2011 Pearl won the Turing Award, computer science’s highest honor, in large part for this work.

But as Pearl sees it, the field of AI got mired in probabilistic associations. These days, headlines tout the latest breakthroughs in machine learning and neural networks. We read about computers that can master ancient games and drive cars. Pearl is underwhelmed. As he sees it, the state of the art in artificial intelligence today is merely a souped-up version of what machines could already do a generation ago: find hidden regularities in a large set of data. “All the impressive achievements of deep learning amount to just curve fitting,” he said recently.

In his new book, Pearl, now 81, elaborates a vision for how truly intelligent machines would think. The key, he argues, is to replace reasoning by association with causal reasoning. Instead of the mere ability to correlate fever and malaria, machines need the capacity to reason that malaria causes fever. Once this kind of causal framework is in place, it becomes possible for machines to ask counterfactual questions—to inquire how the causal relationships would change given some kind of intervention—which Pearl views as the cornerstone of scientific thought. Pearl also proposes a formal language in which to make this kind of thinking possible—a 21st-century version of the Bayesian framework that allowed machines to think probabilistically.

Pearl expects that causal reasoning could provide machines with human-level intelligence. They’d be able to communicate with humans more effectively and even, he explains, achieve status as moral entities with a capacity for free will—and for evil. Quanta Magazine sat down with Pearl at a recent conference in San Diego and later held a follow-up interview with him by phone. An edited and condensed version of those conversations follows.

We asked the experts to answer questions about all the places coronavirus lurks (or doesn’t). You’ll feel better after reading this.

When we asked readers to send their questions about coronavirus, a common theme emerged: Many people are fearful about tracking the virus into their homes on their clothes, their shoes, the mail and even the newspaper.

We reached out to infectious disease experts, aerosol scientists and microbiologists to answer reader questions about the risks of coming into contact with the virus during essential trips outside and from deliveries. While we still need to take precautions, their answers were reassuring.

Should I change my clothes and shower when I come home from the grocery store?

For most of us who are practicing social distancing and making only occasional trips to the grocery store or pharmacy, experts agree that it’s not necessary to change clothes or take a shower when you return home. You should, however, always wash your hands. While it’s true that a sneeze or cough from an infected person can propel viral droplets and smaller particles through the air, most of them will drop to the ground.

Studies show that some small viral particles could float in the air for about half an hour, but they don’t swarm like gnats and are unlikely to collide with your clothes. “A droplet that is small enough to float in air for a while also is unlikely to deposit on clothing because of aerodynamics,” said Linsey Marr, an aerosol scientist at Virginia Tech. “The droplets are small enough that they’ll move in the air around your body and clothing.”
