Four For Friday | July 17, 2026
LF230 | Economists send warning signal about AI, retreats redux, capitalism vs democracy, NYC's PIT Crew + Data viz of the week
Welcome to this week’s Four For Friday. Four topical stories focused on healthspan, systems change and AI for impact. Enjoy!
1. Two hundred top economists raise the alarm about AI
Sixteen Nobel laureates and more than 200 economists and AI researchers have signed “We Must Act Now”, warning that artificial intelligence could reshape the economy more profoundly than the Industrial Revolution, and far faster.
Steam, electricity and computers each granted societies decades to adapt; AI, the signatories argue, may allow only a few years. Organised by Stanford’s Erik Brynjolfsson and colleagues, the statement insists the outcome is not predetermined: whether AI broadly lifts living standards or concentrates wealth depends on institutional choices made now, not once the transformation has arrived. Waiting for certainty, they say, means arriving too late.
The So What: Steam gave us decades to adapt. AI is not that patient.
2. Longevity retreats are the new conference
Three interesting longevity-themed retreats have popped up on my radar that combine longevity / wellness themes with a curated group in a secluded setting.
The Longevity Biotech Fellowship is kicking off its eighth cohort with a retreat in the North Carolina mountains.
Zo Village - invites you to spend a month working on new wellness ventures with a like-minded group of entrepreneurs, in the woods, 2.5 hours from Tokyo.
Next Generation Longevity - hosted in Kyoto by a collection of longevity experts, including Anant Vinjamoori, Chief Medical Officer of hims & hers.
Seems to be a new type of product, reacting to the growth in interest of longevity as well as the desire for (re)connection. It’s fairly meta - both discussing the topic of longevity while ensuring the attendees also benefit from longevity experiences - much improved from the standard conference playbook of sitting all day in a windowless conference room and eating bad food. They all also emphasise community and interconnectedness - arguably longevity’s most significant hack.
The So What: The need to be mindfully present with others is probably the flip-side of our ever-accelerating, screen-centric agent-first world.
3. Capitalism and democracy - poor bedfellows?
I generally assumed that democracy and capitalism are two sides of the same coin - one reinforcing the other. But Jason Hickel argues the case that they’re actually at odds.
Political systems let citizens vote for leaders, yet production, the thing shaping daily life, answers only to capital: the corporations, financial firms and the 1% who own most investible assets.
The result is perverse allocation. Fossil fuels and SUVs get overproduced because they are profitable, while housing, transit and renewables languish. As a result, nearly half of Americans cannot afford healthcare, 4.3 million UK children live in poverty, 95 million Europeans cannot afford decent housing and food.
The “vote with your dollars” defence fails, he says, because one billionaire outvotes 66,000 minimum-wage workers, and you cannot buy what capital declines to make. His remedy is economic democracy: public services, a job guarantee, worker-owned firms and directed credit.
The So What: It’s not really a democracy if you can’t vote on what gets built.
4. NYC is building its own tools to solve problems
New York City’s new Public Interest Technology team, the self-styled PIT Crew, is recruiting engineers, designers, researchers and product managers to build digital public goods in-house.
The pitch is clear: tech once felt good, it no longer does, and governments can do something about it. Rather than outsourcing citizen-facing services to contractors, the city is assembling its own product team with a mandate to make interacting with government dignified and delightful. It is a rebuke to the sprawling, failure-prone procurement model that has long defined civic tech.
The So What: It’s a radical and energising idea - that a government can take charge of building itself, not outsourcing.
Data visualisation of the week
This fun tool allows you to see key demographic information - population pyramid, mortality and fertility - of any country as you zoom around the world, presented in an information-rich and visually appealing way
That’s all for now, happy weekend, everyone.
