US Senator Elizabeth Warren warned that if President Donald Trump eventually moves to fire Federal Reserve Chair Jerome Powell, it could undermine investor confidence in the integrity of US capital markets and trigger a financial crash.
During an appearance on CNBC, the Massachusetts Senator said the President does not have the legal authority to remove Powell from his position. Moreover, removing Powell would weaken the financial infrastructure of the US, Warren added:
“If Chairman Powell can be fired by the President of the United States, it will crash the markets. The infrastructure that keeps this stock market strong and, therefore, a big part of our economy strong, and a big part of the world economy strong, is the idea that the big pieces move independently of politics.”
“If interest rates in the United States are subject to a president who just wants to wave his magic wand, this doesn’t distinguish us from any other two-bit dictatorship,” Warren continued.
President Trump has repeatedly called for Powell’s termination, citing the chairman’s hesitancy to lower interest rates. Lower interest rates are usually considered a positive catalyst for risk-on asset prices, including cryptocurrencies, and could reverse the market downturn brought on by the trade war and current macroeconomic pressures.

Trump’s feud with the Federal Reserve chairman
Trump criticized Powell for not cutting interest rates and called for his termination again in an April 17 Truth Social post, which inflamed speculation that he would follow through on threats and find a way to remove the chairman.
Senator Rick Scott echoed Trump’s calls to remove Powell. “It’s time to clean house of everyone working at the Federal Reserve who isn’t on board with helping the American people and fighting for their best interests,” Scott wrote in an opinion piece published on Fox News.
The Trump administration has repeatedly stated that lowering interest rates is a top priority. Market analyst and investor Anthony Pompliano recently speculated that Trump deliberately crashed financial markets to force lower interest rates.
At the time, Pompliano cited a reduction in the yield of the 10-year US Treasury Bond to just 4%. The 10-year bond yield has climbed back up to 4.3% since then.
Magazine: Meebits and CryptoPunks are like Hot Wheels for adults: New MeebCo owner Sergito
At first glance, the Bathhouse spa in Brooklyn looks not so different from other high-end spas. What sets it apart is out of sight: a closet full of cryptocurrency-mining computers that not only generate bitcoins but also heat the spa’s pools, marble hammams, and showers.
When cofounder Jason Goodman opened Bathhouse’s first location in Williamsburg in 2019, he used conventional pool heaters. But after diving deep into the world of bitcoin, he realized he could fit cryptocurrency mining seamlessly into his business. That’s because the process, where special computers (called miners) make trillions of guesses per second to try to land on the string of numbers that will earn a bitcoin, consumes tremendous amounts of electricity—which in turn produces plenty of heat that usually goes to waste.
“I thought, ‘That’s interesting—we need heat,’” Goodman says of Bathhouse. Mining facilities typically use fans or water to cool their computers. And pools of water, of course, are a prominent feature of the spa.
It takes six miners, each roughly the size of an Xbox One console, to maintain a hot tub at 104 °F. At Bathhouse’s Williamsburg location, miners hum away quietly inside two large tanks, tucked in a storage closet among liquor bottles and teas. To keep them cool and quiet, the units are immersed directly in non-conductive oil, which absorbs the heat they give off and is pumped through tubes beneath Bathhouse’s hot tubs and hammams.
Mining boilers, which cool the computers by pumping in cold water that comes back out at 170 °F, are now also being used at the site. A thermal battery stores excess heat for future use.
Goodman says his spas aren’t saving energy by using bitcoin miners for heat, but they’re also not using any more than they would with conventional water heating. “I’m just inserting miners into that chain,” he says.
Goodman isn’t the only one to see the potential in heating with crypto. In Finland, Marathon Digital Holdings turned fleets of bitcoin miners into a district heating system to warm the homes of 80,000 residents. HeatCore, an integrated energy service provider, has used bitcoin mining to heat a commercial office building in China and to keep pools at a constant temperature for fish farming. This year it will begin a pilot project to heat seawater for desalination. On a smaller scale, bitcoin fans who also want some extra warmth can buy miners that double as space heaters.
Crypto enthusiasts like Goodman think much more of this is coming—especially under the Trump administration, which has announced plans to create a bitcoin reserve. This prospect alarms environmentalists.
The energy required for a single bitcoin transaction varies, but as of mid-March it was equivalent to the energy consumed by an average US household over 47.2 days, according to the Bitcoin Energy Consumption Index, run by the economist Alex de Vries.
Among the various cryptocurrencies, bitcoin mining gobbles up the most energy by far. De Vries points out that others, like ethereum, have eliminated mining and implemented less energy-intensive algorithms. But bitcoin users resist any change to their currency, so de Vries is doubtful a shift away from mining will happen anytime soon.
One key barrier to using bitcoin for heating, de Vries says, is that the heat can only be transported short distances before it dissipates. “I see this as something that is extremely niche,” he says. “It’s just not competitive, and you can’t make it work at a large scale.”
The more renewable sources that are added to electric grids to replace fossil fuels, the cleaner crypto mining will become. But even if bitcoin is powered by renewable energy, “that doesn’t make it sustainable,” says Kaveh Madani, director of the United Nations University Institute for Water, Environment, and Health. Mining burns through valuable resources that could otherwise be used to meet existing energy needs, Madani says.
For Goodman, relaxing into bitcoin-heated water is a completely justifiable use of energy. It soothes the muscles, calms the mind, and challenges current economic structures, all at the same time.

Americans don’t agree on much these days. Yet even at a time when consensus reality seems to be on the verge of collapse, there remains at least one quintessentially modern value we can all still get behind: creativity.
We teach it, measure it, envy it, cultivate it, and endlessly worry about its death. And why wouldn’t we? Most of us are taught from a young age that creativity is the key to everything from finding personal fulfillment to achieving career success to solving the world’s thorniest problems. Over the years, we’ve built creative industries, creative spaces, and creative cities and populated them with an entire class of people known simply as “creatives.” We read thousands of books and articles each year that teach us how to unleash, unlock, foster, boost, and hack our own personal creativity. Then we read even more to learn how to manage and protect this precious resource.
Given how much we obsess over it, the concept of creativity can feel like something that has always existed, a thing philosophers and artists have pondered and debated throughout the ages. While it’s a reasonable assumption, it’s one that turns out to be very wrong. As Samuel Franklin explains in his recent book, The Cult of Creativity, the first known written use of creativity didn’t actually occur until 1875, “making it an infant as far as words go.” What’s more, he writes, before about 1950, “there were approximately zero articles, books, essays, treatises, odes, classes, encyclopedia entries, or anything of the sort dealing explicitly with the subject of ‘creativity.’”
This raises some obvious questions. How exactly did we go from never talking about creativity to always talking about it? What, if anything, distinguishes creativity from other, older words, like ingenuity, cleverness, imagination, and artistry? Maybe most important: How did everyone from kindergarten teachers to mayors, CEOs, designers, engineers, activists, and starving artists come to believe that creativity isn’t just good—personally, socially, economically—but the answer to all life’s problems?
Thankfully, Franklin offers some potential answers in his book. A historian and design researcher at the Delft University of Technology in the Netherlands, he argues that the concept of creativity as we now know it emerged during the post–World War II era in America as a kind of cultural salve—a way to ease the tensions and anxieties caused by increasing conformity, bureaucracy, and suburbanization.
“Typically defined as a kind of trait or process vaguely associated with artists and geniuses but theoretically possessed by anyone and applicable to any field, [creativity] provided a way to unleash individualism within order,” he writes, “and revive the spirit of the lone inventor within the maze of the modern corporation.”

I spoke to Franklin about why we continue to be so fascinated by creativity, how Silicon Valley became the supposed epicenter of it, and what role, if any, technologies like AI might have in reshaping our relationship with it.
I’m curious what your personal relationship to creativity was growing up. What made you want to write a book about it?
Like a lot of kids, I grew up thinking that creativity was this inherently good thing. For me—and I imagine for a lot of other people who, like me, weren’t particularly athletic or good at math and science—being creative meant you at least had some future in this world, even if it wasn’t clear what that future would entail. By the time I got into college and beyond, the conventional wisdom among the TED Talk register of thinkers—people like Daniel Pink and Richard Florida—was that creativity was actually the most important trait to have for the future. Basically, the creative people were going to inherit the Earth, and society desperately needed them if we were going to solve all of these compounding problems in the world.
On the one hand, as someone who liked to think of himself as creative, it was hard not to be flattered by this. On the other hand, it all seemed overhyped to me. What was being sold as the triumph of the creative class wasn’t actually resulting in a more inclusive or creative world order. What’s more, some of the values embedded in what I call the cult of creativity seemed increasingly problematic—specifically, the focus on self-realization, doing what you love, and following your passion. Don’t get me wrong—it’s a beautiful vision, and I saw it work out for some people. But I also started to feel like it was just a cover for what was, economically speaking, a pretty bad turn of events for many people.

Nowadays, it’s quite common to bash the “follow your passion,” “hustle culture” idea. But back when I started this project, the whole move-fast-and-break-things, disrupter, innovation-economy stuff was very much unquestioned. In a way, the idea for the book came from recognizing that creativity was playing this really interesting role in connecting two worlds: this world of innovation and entrepreneurship and this more soulful, bohemian side of our culture. I wanted to better understand the history of that relationship.
When did you start thinking about creativity as a kind of cult—one that we’re all a part of?
Similar to something like the “cult of domesticity,” it was a way of describing a historical moment in which an idea or value system achieves a kind of broad, uncritical acceptance. I was finding that everyone was selling stuff based on the idea that it boosted your creativity, whether it was a new office layout, a new kind of urban design, or the “Try these five simple tricks” type of thing.
You start to realize that nobody is bothering to ask, “Hey, uh, why do we all need to be creative again? What even is this thing, creativity?” It had become this unimpeachable value that no one, regardless of what side of the political spectrum they fell on, would even think to question. That, to me, was really unusual, and I think it signaled that something interesting was happening.
Your book highlights midcentury efforts by psychologists to turn creativity into a quantifiable mental trait and the “creative person” into an identifiable type. How did that play out?
The short answer is: not very well. To study anything, you of course need to agree on what it is you’re looking at. Ultimately, I think these groups of psychologists were frustrated in their attempts to come up with scientific criteria that defined a creative person. One technique was to go find people who were already eminent in fields that were deemed creative—writers like Truman Capote and Norman Mailer, architects like Louis Kahn and Eero Saarinen—and just give them a battery of cognitive and psychoanalytic tests and then write up the results. This was mostly done by an outfit called the Institute of Personality Assessment and Research (IPAR) at Berkeley. Frank Barron and Don MacKinnon were the two biggest researchers in that group.
Another way psychologists went about it was to say, all right, that’s not going to be practical for coming up with a good scientific standard. We need numbers, and lots and lots of people to certify these creative criteria. This group of psychologists theorized that something called “divergent thinking” was a major component of creative accomplishment. You’ve heard of the brick test, where you’re asked to come up with many creative uses for a brick in a given amount of time? They basically gave a version of that test to Army officers, schoolchildren, rank-and-file engineers at General Electric, all kinds of people. It’s tests like those that ultimately became stand-ins for what it means to be “creative.”
Are they still used?
When you see a headline about AI making people more creative, or actually being more creative than humans, the tests they are basing that assertion on are almost always some version of a divergent thinking test. It’s highly problematic for a number of reasons. Chief among them is the fact that these tests have never been shown to have predictive value—that’s to say, a third grader, a 21-year-old, or a 35-year-old who does really well on divergent thinking tests doesn’t seem to have any greater likelihood of being successful in creative pursuits. The whole point of developing these tests in the first place was to both identify and predict creative people. None of them have been shown to do that.
Reading your book, I was struck by how vague and, at times, contradictory the concept of “creativity” was from the beginning. You characterize that as “a feature, not a bug.” How so?
Ask any creativity expert today what they mean by “creativity,” and they’ll tell you it’s the ability to generate something new and useful. That something could be an idea, a product, an academic paper—whatever. But the focus on novelty has remained an aspect of creativity from the beginning. It’s also what distinguishes it from other similar words, like imagination or cleverness. But you’re right: Creativity is a flexible enough concept to be used in all sorts of ways and to mean all sorts of things, many of them contradictory. I think I write in the book that the term may not be precise, but that it’s vague in precise and meaningful ways. It can be both playful and practical, artsy and technological, exceptional and pedestrian. That was and remains a big part of its appeal.
The question of “Can machines be ‘truly creative’?” is not that interesting, but the questions of “Can they be wise, honest, caring?” are more important if we’re going to be welcoming [AI] into our lives as advisors and assistants.
Is that emphasis on novelty and utility a part of why Silicon Valley likes to think of itself as the new nexus for creativity?
Absolutely. The two criteria go together. In techno-solutionist, hypercapitalist milieus like Silicon Valley, novelty isn’t any good if it’s not useful (or at least marketable), and utility isn’t any good (or marketable) unless it’s also novel. That’s why they’re often dismissive of boring-but-important things like craft, infrastructure, maintenance, and incremental improvement, and why they support art—which is traditionally defined by its resistance to utility—only insofar as it’s useful as inspiration for practical technologies.
At the same time, Silicon Valley loves to wrap itself in “creativity” because of all the artsy and individualist connotations. It has very self-consciously tried to distance itself from the image of the buttoned-down engineer working for a large R&D lab of a brick-and-mortar manufacturing corporation and instead raise up the idea of a rebellious counterculture type tinkering in a garage making weightless products and experiences. That, I think, has saved it from a lot of public scrutiny.
Up until recently, we’ve tended to think of creativity as a human trait, maybe with a few exceptions from the rest of the animal world. Is AI changing that?
When people started defining creativity in the ’50s, the threat of computers automating white-collar work was already underway. They were basically saying, okay, rational and analytical thinking is no longer ours alone. What can we do that the computers can never do? And the assumption was that humans alone could be “truly creative.” For a long time, computers didn’t do much to really press the issue on what that actually meant. Now they’re pressing the issue. Can they do art and poetry? Yes. Can they generate novel products that also make sense or work? Sure.
I think that’s by design. The kinds of LLMs that Silicon Valley companies have put forward are meant to appear “creative” in those conventional senses. Now, whether or not their products are meaningful or wise in a deeper sense, that’s another question. If we’re talking about art, I happen to think embodiment is an important element. Nerve endings, hormones, social instincts, morality, intellectual honesty—those are not things essential to “creativity” necessarily, but they are essential to putting things out into the world that are good, and maybe even beautiful in a certain antiquated sense. That’s why I think the question of “Can machines be ‘truly creative’?” is not that interesting, but the questions of “Can they be wise, honest, caring?” are more important if we’re going to be welcoming them into our lives as advisors and assistants.
This interview is based on two conversations and has been edited and condensed for clarity.

The quest for long, healthy life—and even immortality—is probably almost as old as humans are, but it’s never been hotter than it is right now. Today my newsfeed is full of claims about diets, exercise routines, and supplements that will help me live longer.
A lot of it is marketing fluff, of course. It should be fairly obvious that a healthy, plant-rich diet and moderate exercise will help keep you in good shape. And no drugs or supplements have yet been proved to extend human lifespan.
The growing field of longevity medicine is apparently aiming for something in between these two ends of the wellness spectrum. By combining the established tools of clinical medicine (think blood tests and scans) with some more experimental ones (tests that measure your biological age), these clinics promise to help their clients improve their health and longevity.
But a survey of longevity clinics around the world, carried out by an organization that publishes updates and research on the industry, is revealing a messier picture. In reality, these clinics—most of which cater only to the very wealthy—vary wildly in their offerings.
Today, the number of longevity clinics is thought to be somewhere in the hundreds. The proponents of these clinics say they represent the future of medicine. “We can write new rules on how we treat patients,” Eric Verdin, who directs the Buck Institute for Research on Aging, said at a professional meeting last year.
Phil Newman, who runs Longevity.Technology, a company that tracks the longevity industry, says he knows of 320 longevity clinics operating around the world. Some operate multiple centers on an international scale, while others involve a single “practitioner” incorporating some element of “longevity” into the treatments offered, he says. To get a better idea of what these offerings might be, Newman and his colleagues conducted a survey of 82 clinics around the world, including the US, Australia, Brazil, and multiple countries in Europe and Asia.
Some of the results are not all that surprising. Three-quarters of the clinics said that most of their clients were Gen Xers, aged between 44 and 59. This makes sense—anecdotally, it’s around this age that many people start to feel the effects of aging. And research suggests that waves of molecular changes associated with aging hit us in our 40s and again in our 60s. (Longevity influencers Bryan Johnson, Andrew Huberman, and Peter Attia all fall into this age group too.)
And I wasn’t surprised to see that plenty of clinics are offering aesthetic treatments, focusing more on how old their clients look. Of the clinics surveyed, 28% said they offered Botox injections, 35% offered hair loss treatments, and 38% offered “facial rejuvenation procedures.” “The distinction between longevity medicine and aesthetic medicine remains blurred,” Andrea Maier of the National University of Singapore, and cofounder of a private longevity clinic, wrote in a commentary on the report.
Maier is also former president of the Healthy Longevity Medicine Society, an organization that was set up with the aim of establishing clinical standards and credibility for longevity clinics. Other results from the survey underline how much of a challenge this will be; many clinics are still offering unproven treatments. Over a third of the clinics said they offered stem-cell treatments, for example. There is no evidence that those treatments will help people live longer—and they are not without risk, either.
I was a little surprised to see that most of the clinics are also offering prescription medicines off label. In other words, drugs that have been approved for specific medical issues are apparently being prescribed for aging instead. This is also not without risks—all medicines have side effects. And, again, none of them have been proved to slow or reverse human aging.
And these prescriptions are coming from certified medical doctors. More than 80% of clinics reported that their practice was overseen by a medical doctor with more than 10 years of clinical experience.
It was also a little surprising to learn that despite their high fees, most of these clinics are not making a profit. For clients, the annual costs of attending a longevity clinic range between $10,000 and $150,000, according to Fountain Life, a company with clinics in Florida and Prague. But only 39% of the surveyed clinics said they were turning a profit and 30% said they were “approaching breaking even,” while 16% said they were operating at a loss.
Proponents of longevity clinics have high hopes for the field. They see longevity medicine as nothing short of a revolution—a move away from reactive treatments and toward proactive health maintenance. But these survey results show just how far they have to go.
