What if the biggest threat to humanity isn’t a tax policy or a political scandal, but something far more existential? Assistant Treasury Minister Andrew Leigh’s recent remarks have me pondering this very question, and frankly, it’s both unsettling and fascinating. Leigh, in a speech honoring economist Lyndhurst Giblin, argues that the odds of global extinction within the next century could be as high as one in six. Personally, I think this is a wake-up call we can’t afford to ignore, even if it feels like something out of a sci-fi novel.
What makes this particularly fascinating is how Leigh frames the issue through the lens of economics. Economics, often dubbed the ‘dismal science,’ typically deals with resource allocation and efficiency. But Leigh pushes the boundaries, asking: What happens when the ultimate scarcity is the future itself? From my perspective, this isn’t just an academic exercise; it’s a profound challenge to how we think about progress and risk.
One thing that immediately stands out is Leigh’s focus on artificial intelligence and synthetic biology as potential existential threats. While climate change and nuclear war dominate headlines, Leigh suggests that our own technological advancements could be our undoing. This raises a deeper question: Are we so focused on innovation that we’re blind to the dangers it might unleash? What many people don’t realize is that the same systems driving prosperity—AI, biotechnology—could also amplify our fragility. It’s a paradox that feels almost inevitable, yet we rarely discuss it.
A detail that I find especially interesting is Leigh’s call for economists to prioritize ‘survivability’ alongside equity and efficiency. Traditionally, economists haven’t been first responders to existential risks. But Leigh argues they should be. If you take a step back and think about it, this makes sense. Economists are experts in managing scarcity and risk, so why not apply those skills to the biggest risk of all? What this really suggests is that our current frameworks for addressing global threats are woefully inadequate.
Leigh’s speech also highlights a broader cultural blind spot: our tendency to underestimate long-term risks in favor of short-term gains. Modern economies are wired for growth, but as Leigh points out, this growth engine might be sowing the seeds of our destruction. This isn’t just a theoretical concern; it’s a practical one. Governments, businesses, and individuals are all complicit in this myopia. Personally, I think this is where the real challenge lies—not in identifying the risks, but in convincing people to care about them.
What this conversation lacks, in my opinion, is a sense of urgency. Leigh’s warnings are dire, yet they’re often met with skepticism or indifference. Why? Partly because existential risks feel abstract, almost unimaginable. But history is littered with civilizations that collapsed because they failed to see the writing on the wall. If humanity is still in its infancy, as Leigh suggests, then extinction would be more than a tragedy—it would be a squandered potential.
This brings me to a final thought: What if the zombie apocalypse isn’t just a metaphor? Leigh’s speech uses it as a dramatic example, but the underlying message is clear. Whether it’s AI gone rogue, a bioterrorism attack, or some other unforeseen catastrophe, the stakes are the same. We’re not just fighting for our lives today; we’re fighting for the trillions of lives that could come after us. That, to me, is the most compelling reason to take these warnings seriously.
In the end, Leigh’s speech isn’t just about economics or policy—it’s about our collective responsibility to the future. It’s a call to rethink progress, to balance innovation with caution, and to confront the uncomfortable truths about our vulnerability. Personally, I think this is one of the most important conversations we could be having. The question is: Are we ready to listen?
