‘Revolution’: Fed Chair Kevin Warsh says US likely ‘big winner’ in AI race

(NEW YORK) — Federal Reserve Chair Kevin Warsh on Wednesday voiced optimism about artificial intelligence, describing the technology as a “paradigm shift” that would likely make the United States a “big winner in the medium-term.”

“We are in the first or second inning of this revolution,” Warsh said in Sintra, Portugal, at a conference organized by the European Central Bank.

Warsh, who took the helm of the Fed last month, weighed in on the bullish side of an ongoing debate among policymakers, investors and the general public about the potential impact of AI on the labor market and wider economy.

The technology could create jobs and boost productivity, strengthening the economy of the U.S. and other nations, according to Warsh.

“This is a big paradigm shift both for the conduct of our policy and for our economies,” Warsh said. “I think the jobs will be greater. Prosperity will be stronger.”

Business investment in AI has helped drive recent U.S. economic growth, some studies show.

A surge of AI spending accounted for roughly two-thirds of gross domestic product growth over the first half of 2025, JPMorgan Asset Management found, outpacing the contribution made by hundreds of millions of U.S. consumers. Many of the nation’s largest companies have poured funds into the chips and data centers necessary to operate AI.

AI chipmakers, meanwhile, have helped deliver stock market gains this year, allowing the major indexes to overcome a lackluster stretch for many of the tech giants that previously lifted markets.

Shares of fast-rising AI chipmakers have boosted major indexes. Micron has soared 265% in value this year. Sandisk has climbed a staggering 750% over that period.

For now, however, AI has failed to achieve gains on a scale near its immense costs, some analysts previously told ABC News. A product like AI would typically generate revenue in the form of sales either direct to consumers or to third-party businesses using the technology to enhance their offerings. AI has faced challenges on both fronts, some analysts said.

Speaking on Wednesday, Warsh signaled that he expects a shift in sentiment among businesses regarding the impact of AI.

“While we might see business surveys that say ‘no big deal,’ my speculation is six months from now the surveys will be saying quite the opposite,” Warsh said.

Millions of Americans with untreated high blood pressure should be taking medication

By CNN
Nearly 1 in 3 adults in the United States with untreated high blood pressure would benefit from treatment and are not getting it, according to a new study.That’s because nearly 10 million Americans now meet newly updated guidelines by the American Heart Association and American College of Cardiology that redefine an adult’s risk for cardiovascular disease.“We estimated that approximately 200,900 all-cause deaths and 162,600 cardiovascular deaths could be prevented over the next 10 years,” said lead study author Dr. Mustafa Al-Jarshawi, a cardiologist at Keele University in England.Ideally, doctors want blood pressure to fall below 120 mmHg systolic and 80 mmHg diastolic. If blood pressure is around 130/80, doctors have typically advised people to make changes to their lifestyle, such as increasing exercise.If doctors use the American Heart Association’s new PREVENT tool, which considers blood sugar, kidney function and a person’s decade-long risk for heart disease as well as blood pressure, some 81 million Americans would be eligible for blood pressure medications.“What this is saying is that people who have traditionally not been at very high risk are now eligible to be treated with medications more aggressively,” said cardiologist Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver.“Generally, I think when people have additional risk, blood pressure is really the silent killer,” said Freeman, who was not involved with the study.Expanding treatment could save livesThe study, published July 29 in the Journal of the American Heart Association, analyzed National Health and Nutrition Examination Survey data from 2009 to 2018. Newer data is available, but the most up-to-date version of the survey hasn’t been around long enough for researchers to know participants’ cause and time of death.The study examines how death rates might be lower if the 2025 hypertension guidelines were implemented during those years, Al-Jarshawi said.Among 81 million adults with high blood pressure and no cardiovascular disease, nearly 23 million may be newly eligible under the new guidelines. Of those 23 million, 9.7 million were untreated.Becoming eligible to receive blood pressure medication was associated with a 23% lower risk of dying compared with no treatment. When it comes to the chances of dying from a heart-related issue, risk dropped by 50%. The study also found that adults with diabetes would benefit most from treatment. This is because diabetes and high blood pressure often occur together, significantly increasing cardiovascular risk, Al-Jarshawi said.Treatment is more than a medicationAny eligible person shouldn’t hesitate to start taking medication in addition to making lifestyle changes to reduce long-term risks, Al-Jarshawi said.Controlling high blood pressure is a long-term commitment to health, CNN contributor Dr. Leana Wen, an emergency physician and adjunct associate professor at George Washington University, told CNN in a previous article. She recommended looking into a key inventory of five daily habits: level of physical activity, diet, substance use including alcohol and marijuana, stress levels, and a healthy weight.“You don’t have to do everything perfectly to make a difference in your health,” Wen said. She suggests starting with small lifestyle changes. Many people can’t easily reduce stress in their lives, but maybe they can more easily start eating more fruits and vegetables.”The findings of the new study highlight the importance of controlling high blood pressure, Freeman said.“The western world is ailing from a variety of cardiometabolic, kidney diseases,” Freeman said. “High blood pressure amplifies a lot of risk, and we have to do whatever we can to get that risk down and being aggressive about blood pressure is very low-hanging fruit.”However, medication only works when it’s inside the person, and not sitting in the bottle unused, Freeman said. About half of adults in the US with high blood pressure don’t regularly take their prescribed medication, according to a July 2025 study published in the journal JAMA Cardiology.Freeman recommends trying to form a habit, such as keeping your pillbox next to an alarm or toothbrush. That way, when set an alarm for the morning or brush your teeth, you remember to also take the pills.“There’s a way to cue yourself and remind,” Freeman said. “For those people that forget, consider having a small supply in your purse or your wallet or your car, just so you can always remember to take it.”The study’s findings also highlight the need for physicians to be alert to early signs of disease and consider blood pressure treatment, even in younger people, according to Freeman.“We’re seeing a lot more young people now who have chronic disease and diabetes and other things that may be relatively mild, but still at risk, and we need to be even more aggressive,” Freeman said.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
