Reducing Respiratory Diseases
Major progress on reducing respiratory diseases is possible and is both technologically and economically feasible.
A century ago, waterborne diseases levied similar costs to those posed by respiratory viruses like colds and influenza today: endemic, periodically epidemic, and widely accepted as an inevitable feature of human life. Then, at the turn of the twentieth century, we decided they didn’t have to be. Pharmaceutical advances and clean water infrastructure made cholera, typhoid, and dysentery rare across much of the world within a matter of decades.Why haven’t we already seen the same kind of transformation with respiratory viruses? Last August we hosted a symposium at Stripe with ~40 leading scientists, pharma R&D leaders, biotech venture capitalists, and regulatory experts to better understand if this is technically possible and, if so, why it hasn’t happened yet.We heard two main reasons. First, it’s just technically very challenging: respiratory viruses represent hundreds of distinct, mutating strains across several families. Fortunately, new platform technologies, advances in our understanding of human immunology, biological data sets, and protein design tools mean we have our strongest ever suite of approaches for tackling it.Second, the development of the broad-spectrum solutions needed to solve the first problem has historically been underfunded, neither a great fit for philanthropic nor commercial funding. While COVID generated a burst of activity around preventing and understanding respiratory infections through an influx of new funding, that hasn’t been sustained.We believe that with enough focus and funding, these problems are tractable. Intercept is a $500 million philanthropic initiative that will take advantage of these new tools to catalyze the development of two types of products: broad-spectrum preventatives and air cleaning technologies. Together, these technologies can radically reduce the burden of respiratory infections, and can eventually help eliminate them altogether.
Why this mattersToday, we treat respiratory infections like the cold and influenza as a minor nuisance. The evidence increasingly suggests otherwise.* Healthy people spend roughly 15-25 days each year—about 5% of their lives—sick with respiratory infections like the common cold and influenza.1* Common respiratory infections can lead to severe outcomes. In 2021 alone, there were 12.8 billion infections globally, mostly caused by viruses.2 Annually, over 65 million3 4 of these progress to serious lower respiratory disease and account for around 7% of deaths from major causes in the U.S.5 6 7* Respiratory infections raise our risk of serious illness, often years later. While researchers are still early in establishing these connections, it seems plausible that society has meaningfully underestimated the significance of seemingly benign infections on short and long-term health, e.g.:** 9.8x asthma risk by age 6 if infected with HRV between birth and age 3 in a high-risk cohort8** 6.1x heart attack risk for 7 days after influenza infection9** 4.5-5x dementia risk after severe influenza10** 2.6-4.1x Alzheimer’s risk after severe influenza and pneumonia11** 2.2-3x schizophrenia potential risk for infant if mother is infected by influenza during pregnancy12 13** 1.3x risk of heart failure after RSV infection compared to influenza14* Routine respiratory illness imposes a massive, persistent economic burden, driving 1–1.5% annual productivity losses—roughly $600B globally, or ~0.6% of global GDP—in non-pandemic years.15* Emerging evidence suggests that severe prenatal16 17 and early postnatal18 respiratory infections might lead to reduced adult earnings and educational attainment later in life.* Achieving broad protection against respiratory pathogens would meaningfully reduce pandemic risk, serving as a critical first line of defense—alongside air disinfection—against both natural outbreaks and increasingly accessible engineered biological threats.
Two technologies, working togetherNo single technology can accomplish population-level infection reduction across all of these pathogens. A shot or pill that provided >90% protection against >90% of respiratory viruses (we’ll call these broad-spectrum preventatives or BSPs), but achieved ~60% uptake (a realistic ceiling based on existing vaccine uptake), would still fall short of of the population immunity required to dramatically reduce sustained transmissions.This is because there are so many different kinds of respiratory viruses, many of which are highly contagious. It’s helpful to revisit the concept of R0 from the COVID pandemic: the number of people an infected person will infect in a fully unprotected population. While we can’t change the intrinsic R0 of a given virus, we can reduce any given virus’s effective reproduction number (Re): how infective a virus is in a given environment inclusive of interventions. To eliminate a virus, its Re needs to drop below 1. The vast majority of seasonal respiratory viruses have an R0 between 1 and 3. To eliminate an R3.0 virus, you need roughly 67% of the population to be protected.So, to get closer to elimination, we also need a way to reduce the virions circulating in high density environments. During COVID the world experimented with various interventions like social distancing and personal protective equipment. But to reduce transmission durably for a large number of common respiratory viruses that are perennially circulating, we need solutions that are convenient and minimally disruptive.We think the most promising category of products that accomplish these goals are those that remove pathogens from the air, particularly in high-density environments like offices, schools, and public transit. We’ll call these air cleaning technologies (ACTs) like air filtration and far-UVC antimicrobial light.The uptake required for BSPs or for ACTs to be effective by themselves is extremely high. As a benchmark, commercial fire sprinkler penetration is about 40% in the US. Getting to 100% uptake would be extremely difficult. But when deployed together at realistic levels, BSPs and ACTs could achieve our goals.

U.K. Navy Makes Smarter Decision Than U.S. Navy
The U.K.'s Navy, unlike the U.S. Navy, understands that building more 1980s era concept destroyers no longer makes sense. They've been paying attention to the Ukraine War in the Black Sea in which traditional surface combatants are being felled by drones.
The U.S. hasn't been and instead is working on a "Trump-class Battleship" which is precisely the wrong direction, and more Arleigh Burke class destroyers.
Navy to build drone-equipped warships instead of replacing ageing destroyersPA MediaPlans to replace ageing warships will be scrapped in favour of building at least six new modern "hybrid" vessels equipped to deploy drones as part of the UK's upcoming defence strategy.The Ministry of Defence (MoD) said the new vessels would be more suited to the "pace and nature of modern warfare", and a better investment than a "small number of large expensive ships".Defence Secretary Dan Jarvis said the new equipment would be "designed and built for the increasing threats we face".Outgoing Prime Minister Sir Keir Starmer has committed to publishing the long-delayed defence investment plan (DIP) before the Nato summit in Turkey on 7 July after months of talks over how to fund it.The MoD had been exploring options to replace the Type 45, the Navy's fleet of destroyers, with the Type 83, a concept vessel which was at an early design phase.Instead, investment will now go towards six new Common Combat Vessels, which the department said would be capable of "coordinating uncrewed systems in the air, on the surface and under the sea to deliver more resilient air defence".It said the change in approach would extend "the Navy's reach, resilience and firepower without a proportional increase in crew or cost".

How We Got Here, And Where We Might Go Next

Planetary Defense Is Worth It
I will always be a strong supporter of a strong planetary defense against comets and asteroids. These "Black Swan" events are rare, but the consequences of even one of them striking Earth and doing great damage would be immense.
If they are headed towards Earth's surface and too large for our atmosphere to provide an adequate defense against, they are always the "bad guy."
There are estimated to be about 45 undiscovered mass extinction class near Earth asteroids, about about 13,750 undiscovered "city killer" sized near Earth asteroids (that would destroy everything in a whole metro area of a major city, if it hit one, killing millions of people), and about 214,000 Hiroshima blast sized near Earth asteroids out there. These asteroids could strike us with short notice. The asteroids wouldn't create the radiation blast and contamination of a nuclear bomb (or highly toxic chemical weapon), but would have comparable kinetic impact to a nuclear bomb.
We need both better asteroid detection technologies (which NASA's new NEO Surveyor mission which is scheduled to launch in Septemer of 2027, twenty-one years after it was proposed, will profoundly improve) and better asteroid interception technologies that can respond to incoming asteroids and comets on short notice (i.e. many hours to several days), which is not currently in place, although rudimentary and ad hoc ICBM responses could be devised that could mitigate the harm if done right (but could make things worse if it diverts a large fragment or cluster of fragments from an uninhabited area towards a city).

The NEO Surveyor mission is projected to:
- Find 2⁄3 of Asteroids Larger than 140 Meters in Diameter
- Assess the Overall Threat Posed by Potential Earth Impactors
- Assess the Impact Threat Posed by Comets
- Determine Orbits and Physical Characteristics of Specific Discovered Objects
We are sufficiently technologically advanced at this point to build adequate planetary defenses, but organizing the planet to fund and deploy them is another matter. The NEO Surveyor mission cost $500 million to $600 million, which is less than a single major U.S. warship or Air Force long range bomber, or several start of the art U.S. Air Force fighter jets. Military missile defense technologies (like the "Golden Dome" plan for the U.S.) can be adapted for planetary defense purposes, to some extent, but aren't optimized for this task.
The good news is that the many millions or more smaller asteroids and space junk objects mostly burn up in the atmosphere before hitting Earth with enough damage to be much more dangerous than a random and rare lightning strike. So, we harm from not tracking or intercepting them is modest.
Also, a huge share of the Earth's surface is made up of oceans, large lakes, uninhabited ice scapes, thinly inhabited mountains and deserts, and thinly inhabited rural areas or wilderness. A "city killer" or smaller asteroid has a quite localized danger zone and isn't radioactive or toxic for the most part.
So, while it might kill or injure a small number of people in the immediate vicinity of the impact, and might trigger a significant tsunami or landslide (urban areas are disproportionately coastal), about 71% of Earth's surface is water, about 28% of Earth's surface is nearly uninhabited or rural, and only about 1% of Earth's surface is urban. So, most "city killer" or smaller extraterrestrial impacts would lead to fairly modest casualties. But the risk of mass casualties from an extraterrestrial impact is much greater now than it was for most of human history, because the world's population has grown so much and is concentrated in cities.
This analysis assumes that all locations on Earth are equally at risk, which isn't strictly speaking true, but is a close enough approximation of the reality to be a useful starting point.
While there have been only a handful of attested really big extraterrestrial impacts in human history, and only a few more than we have clear evidence of in the last 300,000 years or so when the human species came into being, there have probably been hundreds, if not several thousand that went unnoticed because they landed in uninhabited areas, or left no survivors in thinly populated areas and didn't leave any traces clear enough to attested to their impacts geologically before their impacts were eroded away.
More than half of the “city killer” asteroids that might threaten Earth remain undiscovered. With an infrared eye, NASA’s NEO Surveyor aims to find them.
Russia Has Lost 30% Of Its Black Sea Fleet
Ukraine has done a remarkable job to degrading Russia's Black Sea naval fleet for a country without a navy of its own.
Russia’s Black Sea Fleet was once a dominant regional naval force. But the fleet has been severely weakened, resulting in a shift from an offensive force to a defensive “fleet-in-being.” What’s notable about the fleet’s degradation is that Ukraine didn’t need a traditional navy to inflict it; rather, it used drones, missiles, and targeting to strip the Black Sea Fleet of its ability to operate, offering another example of asymmetric, cheap measures crippling traditional, expensive military platforms.Russia is believed to have lost 30 percent of its Black Sea Fleet, either to damage or outright destruction. That’s 24–29 vessels lost. Key losses include the flagship vessel, the Moskva cruiser, and multiple landing ships.The remaining strike force consists of seven offensive warships, including two frigates, three corvettes, and two submarines. So the fleet still exists, but its offensive capabilities have collapsed. . . .
The primary weapon in the fleet’s arsenal is the Kalibr cruise missile. Before the Russo-Ukrainian War, the fleet had the capability to launch large missile salvos. But now the Kalibr can be launched from just five surface ships and two submarines, limiting the fleet’s ability to launch its pre-war missile salvos. . . .
Loss of Bases
Ukraine has also targeted Russian naval bases. Sevastopol, the primary naval hub, has been repeatedly struck, forcing the fleet to relocate. But the new base, Novorossiysk, has also been under attack.
The result has been that Russia no longer has a secure naval base in the Black Sea, which has obviously degraded its ability to maintain a meaningful presence there. And now, with the fleet concentrated in Novorossiysk, Ukraine has a base under constant drone threat, limiting the fleet’s ability to maneuver.As a defensive measure, the ships rarely leave port, and the submarines hide near the bases. So the existing fleet is effectively contained—still present but operationally inactive.Missile Capability Degradation
Maintenance CollapseThe fleet has suffered from a maintenance collapse. The core issue is that there is no dry dock, and the Bosporus Strait has been closed. The result is that no major repairs have been made, and overall readiness has been severely degraded.Damaged ships have been forced to simply remain damaged, meaning that even ships that survive are slowly losing their effectiveness. . . .
Strategic Implications
The destruction of Russia’s Black Sea Fleet suggests that large ships are now vulnerable to cheap and effective drones that adversaries can deploy in swarms.Sea control has been redefined; Ukraine does not have a traditional navy, yet it still managed to deny Russia’s ability to use a traditional navy to control the seas.The global lesson here is that fleets can be neutralized without a fleet-on-fleet battle. The Black Sea may offer a glimpse into the future of naval warfare, where distributed, low-cost systems are effective counters to legacy systems.

Apache AH-64 Gunships On Ships
I've been a longtime advocate of using Apache AH-64 helicopter gunships on naval ships, particularly in roles like piracy suppression on otherwise lightly armed ships, like the Littoral Combat Ships.
Now, the U.S. Navy is now considering the idea.

Oil And Water
Scarcity of oil and rising petroleum prices, and climate change driven drought, are a big deal. But there are fairly clear paths by which our society can adapt to both. Neither would be apocalyptic, even though it would drive significant, visible changes in our day to day material culture.
These matters are particularly worth thinking about on Earth Day, which is today.
Oil
A very large share of all petroleum consumption is for transportation, mostly cars, trucks, construction vehicles, boats, ships, and trains. Advances in battery technology, and EV manufacturing and infrastructure are making electric vehicle alternatives to all of those technologically viable. And, advances in renewable energy and nuclear power can replace almost all of the fossil fuels in the electrical power grid. Coal is well on its way to be phased out in the United States and much of the developed world. Alaska and Hawaii are the only U.S. states where a significant share of electricity is generated from petroleum. Heat pumps are paving the way as an alternative to heating buildings that were historically heated with heating oil in the U.S. (mostly in the Northeast).
Heat pumps and evaporative coolers (together with better insulation) also dramatically more energy efficient than conventional air conditioning, and renewables like solar and wind combined with modern batteries are particularly well suited to meet the demand for electricity to provide cooling.
Lots of fertilizers that are petroleum based could also become unaffordable, as they have as global petroleum supplies have been interrupted by U.S. and Israeli attacks on Iran, and its counterattacks. But organic farming techniques are now well established enough that these methods pose an obvious alternative path for agriculture is petroleum based fertilizers cease to become economically viable. Dutch models of intensive hydroponic agriculture suggests another off ramp from what is now considered conventional agriculture.
There are some applications where there aren't good alternatives to petroleum, like plastics and jet fuel. But these are such a small share of total petroleum consumption that these uses could be sustained, even if they become more expensive, even if petroleum prices soar and the supplies contract greatly.
Of course, plastics and petroleum based fabrics like nylon, have only been in wide use for about sixty years. If plastic becomes too expensive, we can revert to using metal, glass, wood, and plant and animal fiber alternatives for applications like kitchen ware and trash bins that aren't uniquely suited to plastic, as traditional alternatives becomes more affordable relative to plastic with rising petroleum prices.
The changes wouldn't be geographically neutral. A collapse in demand for petroleum driving by electric vehicles and organic farming would crush the economies of petrostates in the Middle East, in Brunei, in Nigeria, in Venezuela, and in select states within the United States. West Virginia has already seen its coal based economy collapse, as have many historically coal mining economy based regions in Europe. Wyoming will follow suit.
On the other hand, rare earth rich areas who supply key components of modern batteries and electronics, may see mineral economy booms.
Water
In most of the arid west, marginal agricultural activity consumes 80%-90% of all fresh water, while landscaping and golf courses consume about half of the rest of the fresh water. If water becomes scarce, entire regions can eliminate their water hungry landscaping, golf courses can close or become much more expensive or use artificial grass, and marginal agricultural operations can close.
In places like the Arabian Peninsula, Greece, Utah, and California, desalination technology might become more prominent as a water source, at least for high value municipal waters uses like drinking, cooking, and bathing, and gray water systems would use non-potable water (such as salt water from the ocean or salt water lakes) in applications where drinkability wasn't important, like flushing toilets.
Climate change that produces global warming ultimately both gives and takes away arable land. It renders much of the arid West unsuitable for farming and ranching, but makes places that were too cold for farming in the past, more suitable for it. Even when climate change doesn't actually change the total amount of arable land somewhere, it may change the kind of agriculture that is appropriate in that place.
Places that used to support subtropical orange groves may freeze more often and get dryer and become more suitable for cotton and the soft wheat varieties currently grown in places north of Florida in the American South. Crops now grown in the South might start to be grown in the Midwest. The abundant corn and wheat fields of the Great Plains and Midwest might move north to Canada. The Great Plains might transition from grain farming to cattle grazing.
I'm not a climate scientist. I don't have exact models of exactly when and where climate zones that are suitable for particular crops and livestock will relocate. But that's the basic concept.
The ongoing wars across the Sahel of Africa illustrate how ugly the process of having herders ecologically forced into historically horticultural land can be without strong geographically large states to force the transition to be made with money instead of violence can look. But with strong states that remove violence as a viable option, the transition, while still massively disruptive, could be less tragic in places like North America and Western Europe.
Similarly, the skiing industry might relocate from places like Colorado and Vermont to places like the Yukon and Alaska, in North American, and from places like the Alps in Europe to the northern Urals and the Himalayas in Eurasia.
Many Sunbelt communities in places like Arizona and Texas and Florida may see the waves of migration to avoid the cold winters of the north replaced by migration north to avoid the months of hundred degree plus water in the Sunbelt which are already commonplace in cities like Phoenix and Las Vegas, while the rust belt, with its winters made milder due to global warming and abundant fresh water, may start to look more attractive, and may attract mass return migrations.
One of these days, people in the Sunbelt may return to the traditional solution of having midday siestas, inside cooler, shaded adobe insulated homes, and becoming more active once the sun goes down and the air cools late into the evening.
Coastal communities will have to build dikes or lose land area as sea levels rise, and many will have to remake their architectural landscape in the face of increasingly severe storms, something that will hit the U.S. states of Florida and Louisiana and some islands in Oceania particularly hard.
Species limited to narrow microenvironment ranges will go extinct en masse, as human encroachment upon their habitats, ecological disruption, and human predation have already done to many species already.
How fast will it happen?
We are, in 2026, at about the place on this path that we thought we'd be in the year 2006, back in 1986. Events like the transitions to EVs and heat pumps and renewables and industrial scale organic farming happened, but it took about twice as long as futurists at the time thought that it would.
Climate change, on the other hand, is happening faster than expected by a decade or three. The changes that were initially looking like they would take a century to run their course are now looking like they will occur in half of that time.
Certainly, these transitions are medium to long run trends. They will probably takes decades more to run their course. These transitions probably won't be complete in my lifetime, although they probably will run their course in the lives of my children, or at least, in the lives of my future grandchildren. Less poetically, this time frame is about 30-90 years.
But these trends are both massive and inexorable, like plate tectonics but much, much faster. Fast enough that it will be visible in future tree ring records.
Conclusion
These are huge, traumatic changes that will force mass migrations and fundamental changes in people's day to day culture. But they don't mean the end of modern life as we know it either. And falling birthrates will eventually lead to smaller global and regional populations that put less strain on scarce water and fossil fuel resources.
