Now that President Trump has announced that he'll be nominated Kevin Warsh to chair the Fed, I thought I'd repost my interview with Kevin of last spring. A fascinating overview of the economy, the Fed, and Kevin's own mind. "Inflation should be so low nobody even talks about it."

Revenue per employee up 75% for the top decile of AI/software companies in 2025. Probably doesn’t slow down in 2026 given the December revolution in AI coding agents.
Nothing to see here, move along.
No evidence of AI productivity anywhere.
With a week to reflect, I’m convinced this was the greatest moment in sports history.
A 2-star recruit leads the worst program ever to a national championship, beats his hometown team that wouldn’t let him walk on, and finishes it by running over the same guy who knocked him out the year before, with his mother battling MS watching from the stands.
If it was a Disney movie, you’d say it was too much.
@FoundersPodcast @ethan_frost1 I wish there was a network for people that have crossed 100 Founders episodes. 50 is cool and all but when you cross 100 it couldn’t possibly be more clear that you get it.
Clear signal of who to:
Hire
Work for
Partner with
Invest in
Raise from
Collaborate with
Loan to
Etc
“Every major shift, from the printing press to electricity to the steam engine, sparked fears of job loss and social collapse. In 1800, 70-80% of Americans worked in agriculture. By 1900, it was roughly 40%. Today it’s <2%. We didn’t become obsolete. We found new callings.”
Agency > Intelligence
I had this intuitively wrong for decades, I think due to a pervasive cultural veneration of intelligence, various entertainment/media, obsession with IQ etc. Agency is significantly more powerful and significantly more scarce. Are you hiring for agency? Are we educating for agency? Are you acting as if you had 10X agency?
Grok explanation is ~close:
“Agency, as a personality trait, refers to an individual's capacity to take initiative, make decisions, and exert control over their actions and environment. It’s about being proactive rather than reactive—someone with high agency doesn’t just let life happen to them; they shape it. Think of it as a blend of self-efficacy, determination, and a sense of ownership over one’s path.
People with strong agency tend to set goals and pursue them with confidence, even in the face of obstacles. They’re the type to say, “I’ll figure it out,” and then actually do it. On the flip side, someone low in agency might feel more like a passenger in their own life, waiting for external forces—like luck, other people, or circumstances—to dictate what happens next.
It’s not quite the same as assertiveness or ambition, though it can overlap. Agency is quieter, more internal—it’s the belief that you *can* act, paired with the will to follow through. Psychologists often tie it to concepts like locus of control: high-agency folks lean toward an internal locus, feeling they steer their fate, while low-agency folks might lean external, seeing life as something that happens *to* them.”
This is the category-defining profile of one of the most important figures and institutions in American business, investing, and technology.
Joshua Kushner and Thrive Capital.
Kushner and his partners speak, as do Sam Altman, Jony Ive, Demis Hassabis, and John Collison.
It’s a story of the American dream. One that travels from the Holocaust in Eastern Europe through postwar Budapest, a refugee camp in Rome, Cold War New York and New Jersey, post-9/11 America, the recent history of venture capital, the AI revolution, wartime Israel, and Rick Rubin’s backyard.
It tells, with fresh eyes and ears, what happened during the 2023 OpenAI coup attempt. It takes you inside critical moments at Stripe and GitHub. And it shows how Kushner’s team of émigré and provincial castaways built Thrive into a rampart for the American experiment.
The ending will give you goosebumps.

Nine years ago, I launched Founders (@FoundersPodcast).
Today, I'm launching a new podcast called David Senra.
The first episode goes live this Sunday. Subscribe wherever you watch or listen to podcasts.
Founders will still come out every week.

"We are being afflicted with a new disease of which some readers may not yet have heard the name, but of which they will hear a great deal in the years to come – namely, technological unemployment."

Incorrect. Independent pharmacies will stay in business , resulting in more
And with the protections more can open
Pharmacies deserve to be paid. Not to be used as a source of rebates to enrich PBMs ans insurance companies
