#224 – There's a cheap and low-tech way to save humanity from any engineered disease | Andrew Snyder-Beattie

Conventional wisdom is that safeguarding humanity from the worst biological risks — microbes optimised to kill as many as possible — is difficult bordering on impossible, making bioweapons humanity’s single greatest vulnerability. Andrew Snyder-Beattie thinks conventional wisdom could be wrong.

Andrew’s job at Open Philanthropy is to spend hundreds of millions of dollars to protect as much of humanity as possible in the worst-case scenarios — those with fatality rates near 100% and the collapse of technological civilisation a live possibility.

As Andrew lays out, there are several ways this could happen, including:

  • A national bioweapons programme gone wrong, in particular Russia or North Korea
  • AI advances making it easier for terrorists or a rogue AI to release highly engineered pathogens
  • Mirror bacteria that can evade the immune systems of not only humans, but many animals and potentially plants as well

Most efforts to combat these extreme biorisks have focused on either prevention or new high-tech countermeasures. But prevention may well fail, and high-tech approaches can’t scale to protect billions when, with no sane people willing to leave their home, we’re just weeks from economic collapse.

So Andrew and his biosecurity research team at Open Philanthropy have been seeking an alternative approach. They’re proposing a four-stage plan using simple technology that could save most people, and is cheap enough it can be prepared without government support. Andrew is hiring for a range of roles to make it happen — from manufacturing and logistics experts to global health specialists to policymakers and other ambitious entrepreneurs — as well as programme associates to join Open Philanthropy’s biosecurity team (apply by October 20!).

Fundamentally, organisms so small have no way to penetrate physical barriers or shield themselves from UV, heat, or chemical poisons. We now know how to make highly effective ‘elastomeric’ face masks that cost $10, can sit in storage for 20 years, and can be used for six months straight without changing the filter. Any rich country could trivially stockpile enough to cover all essential workers.

People can’t wear masks 24/7, but fortunately propylene glycol — already found in vapes and smoke machines — is astonishingly good at killing microbes in the air. And, being a common chemical input, industry already produces enough of the stuff to cover every indoor space we need at all times.

Add to this the wastewater monitoring and metagenomic sequencing that will detect the most dangerous pathogens before they have a chance to wreak havoc, and we might just buy ourselves enough time to develop the cure we’ll need to come out alive.

Has everyone been wrong, and biology is actually defence dominant rather than offence dominant? Is this plan crazy — or so crazy it just might work?

That’s what host Rob Wiblin and Andrew Snyder-Beattie explore in this in-depth conversation.

The 80,000 Hours Podcast, from The 80,000 Hours team, digs into the complex and often overlooked questions surrounding how we can best use our careers to tackle the world's most pressing problems. While artificial intelligence is a recurring and critical theme, framing some of the most important conversations you won't hear elsewhere, the discussions range far wider into the intersections of technology, policy, philosophy, and global priorities. Hosts Rob Wiblin, Luisa Rodriguez, and Zershaaneh Qureshi guide in-depth interviews with researchers, policymakers, and practitioners, breaking down daunting ideas into actionable insights. You'll hear nuanced analyses of career paths, ethical dilemmas in emerging tech, and evidence-based strategies for creating a positive impact. This isn't about quick tips; it's about deep, substantive exploration of how specific choices and systemic changes can lead to a better future. The podcast lives in the Education and Technology categories because it fundamentally aims to equip listeners with the knowledge and perspective to navigate a rapidly changing world thoughtfully. Each episode is built on rigorous research, challenging assumptions while maintaining a conversational and accessible tone. Tune in for a consistently engaging and intellectually honest look at the forces shaping our century and the practical steps individuals can take within their own 80,000-hour working lives to make a meaningful difference.
