It’s easy to survey the last 10 days in America and be flabbergasted at President Trump’s tendency to inflict politically bruising crises on himself. I know this because I had just that reaction on Wednesday, trying to make sense of his abrupt signing of an executive order intended to end separations of unauthorized immigrant families at the border. The current moment is more acute than others, but it follows the template set by the aftermath of a white-supremacist march in Charlottesville, Virginia; brinksmanship with North Korea; the collapse of Obamacare repeal; the firing of James Comey; and any number of smaller, half-forgotten crises. Why doesn’t he learn?

But maybe the truth is that Trump keeps creating crises because he needs them.

The drive to the little white dome on the northern slope of Mauna Loa is a bumpy one. Mauna Loa, the “Long Mountain,” is a colossal volcano that covers half of the island of Hawaii. The rocky terrain, rusty brown and deep red, crunches beneath car tires and jostles passengers. Up there, more than 8,000 feet above sea level and many miles away from the sounds of civilization, it doesn’t feel like Earth. It feels like another planet. Like Mars.

For the past five years, small groups of people have made this drive and moved into the dome, known as a habitat. Their job is to pretend that they really are on Mars, and then spend months living like it. The goal, for the researchers who send them there, is to figure out how human beings would do on a mission to the real thing.

Enrico Fermi was an architect of the atomic bomb, a father of radioactivity research, and a Nobel Prize–winning scientist who contributed to breakthroughs in quantum mechanics and theoretical physics. But in the popular imagination, his name is most commonly associated with one simple, three-word question, originally meant as a throwaway joke to amuse a group of scientists discussing UFOs at the Los Alamos lab in 1950: Where is everybody?

Fermi wasn’t the first person to ask a variant of this question about alien intelligence. But he owns it. The query is known around the world as the Fermi paradox. It’s typically summarized like this: If the universe is unfathomably large, the probability of intelligent alien life seems almost certain. But since the universe is also 14 billion years old, it would seem to afford plenty of time for these beings to make themselves known to humanity. So, well, where is everybody?

Three years ago, Lisa Linh quit her full-time job to travel the world and document it on Instagram, where she has nearly 100,000 followers; since then, she has stayed in breathtaking hotels everywhere from Mexico to Quebec to the Cook Islands. Often, she stays for free.

Linh is part of an ever-growing class of people who have leveraged their social media clout to travel the world, frequently in luxury. While Linh and other elite influencers are usually personally invited by hotel brands, an onslaught of lesser-known wannabes has left hotels scrambling to deal with a deluge of requests for all-expense-paid vacations in exchange for some social media posts.

Kate Jones, marketing and communications manager at the Dusit Thani, a five-star resort in the Maldives, said that her hotel receives at least six requests from self-described influencers per day, typically through Instagram direct message.

Claire is a 14-year-old girl with short auburn hair and a broad smile. She lives outside Philadelphia with her mother and father, both professional scientists. Claire can come across as an introvert, but she quickly opens up, and what seemed like shyness reveals itself to be quiet self-assuredness. Like many kids her age, she is a bit overscheduled. During the course of the evening I spent with Claire and her mother, Heather—these aren’t their real names—theater, guitar, and track tryouts all came up. We also discussed the fact that, until recently, she wasn’t certain she was a girl.

Sixth grade had been difficult for her. She’d struggled to make friends and experienced both anxiety and depression. “I didn’t have any self-confidence at all,” she told me. “I thought there was something wrong with me.” Claire, who was 12 at the time, also felt uncomfortable in her body in a way she couldn’t quite describe. She acknowledged that part of it had to do with puberty, but she felt it was more than the usual preteen woes. “At first, I started eating less,” she said, “but that didn’t really help.”

For Markus Heilig, the years of dead ends were starting to grate.

A seasoned psychiatrist, Heilig joined the National Institutes of Health in 2004 with grand ambitions of finding new ways to treat addiction and alcoholism. “It was the age of the neuroscience revolution, and all this new tech gave us many ways of manipulating animal brains,” he recalls. By studying addictive behavior in laboratory rats and mice, he would pinpoint crucial genes, molecules, and brain regions that could be targeted to curtail the equivalent behaviors in people.

It wasn’t to be. The insights from rodent studies repeatedly proved to be irrelevant. Many researchers and pharmaceutical companies became disillusioned. “We cured alcoholism in every rat we ever tried,” says Heilig, who is now at Linköping University in Sweden. “And at the end of every paper, we wrote: This will lead to an exciting treatment. But everything we took from these animal models to the clinic failed. We needed to go back to the drawing board.”

The ashes filled a black plastic box about the size of a toaster. It weighed three and a half pounds. I put it in a canvas tote bag and packed it in my suitcase this past July for the transpacific flight to Manila. From there I would travel by car to a rural village. When I arrived, I would hand over all that was left of the woman who had spent 56 years as a slave in my family’s household.

1. The Aristocracy Is Dead …

For about a week every year in my childhood, I was a member of one of America’s fading aristocracies. Sometimes around Christmas, more often on the Fourth of July, my family would take up residence at one of my grandparents’ country clubs in Chicago, Palm Beach, or Asheville, North Carolina. The breakfast buffets were magnificent, and Grandfather was a jovial host, always ready with a familiar story, rarely missing an opportunity for gentle instruction on proper club etiquette. At the age of 11 or 12, I gathered from him, between his puffs of cigar smoke, that we owed our weeks of plenty to Great-Grandfather, Colonel Robert W. Stewart, a Rough Rider with Teddy Roosevelt who made his fortune as the chairman of Standard Oil of Indiana in the 1920s. I was also given to understand that, for reasons traceable to some ancient and incomprehensible dispute, the Rockefellers were the mortal enemies of our clan.

Smartphones have by now been implicated in so many crummy outcomes—car fatalities, sleep disturbances, empathy loss, relationship problems, failure to notice a clown on a unicycle—that it almost seems easier to list the things they don’t mess up than the things they do. Our society may be reaching peak criticism of digital devices.

Even so, emerging research suggests that a key problem remains underappreciated. It involves kids’ development, but it’s probably not what you think. More than screen-obsessed young children, we should be concerned about tuned-out parents.

Yes, parents now have more face time with their children than did almost any parents in history. Despite a dramatic increase in the percentage of women in the workforce, mothers today astoundingly spend more time caring for their children than mothers did in the 1960s. But the engagement between parent and child is increasingly low-quality, even ersatz. Parents are constantly present in their children’s lives physically, but they are less emotionally attuned. To be clear, I’m not unsympathetic to parents in this predicament. My own adult children like to joke that they wouldn’t have survived infancy if I’d had a smartphone in my clutches 25 years ago.

Conservatives have been able to abide these decidedly anti-family policies through an embrace of white nationalism, which deems brown skinned men, women and children of degraded humanity—and therefore absent any inherent value and unworthy of protection .
