It took me seven months to get my baby an Australian passport

I’m an Australian father of four, living in the US. Something of a corner case. Nevertheless, getting my kids Australian citizenship by descent, and then Australian passports so we can fly home legally, has kicked off a carnival of errors with a very dark side. Australia is generally thought of as a developed western liberal country with relatively high state capacity. And I have generally found that at least state government services, now administered through centralized offices, have become more efficient over time. Passport applications for children living overseas, however, remain a time machine with a difficult security overhang. Australian …

How deep is Tulainyo Lake?

Regular readers may recall that I put a visit to Tulainyo Lake on my bucket list a few years ago. Last week I did it. Impossibly remote, otherworldly beauty, and an enduring mystery. Just how deep was this lake? Wikipedia claims not to know. Measuring it is non-trivial. A worthy challenge. The skinny: This relatively small alpine lake is about 117 m deep! That makes it the 25th deepest natural lake in North America, and by far the deepest lake on Earth for its size. Enjoy our interactive report here.

How to build a crazy awesome Australian immigration system

The Australian immigration system must exclude dickheads, bullshitters, and bludgers. This post has been inspired by Joe Walker’s recent set of three exemplary interviews (Martin Parkinson (former Treasury, author of 2023 migration review), Mark Cully (historian), Mike Pezzullo (senior border official 2013-2023))  on the subject of immigration policy. This comes against a backdrop of growing scepticism within the West on current levels of immigration, concerns about integration, cultural compatibility, rising costs of living, straining public services and infrastructure, and the rapidly increasing popularity of hardline anti-immigration political parties who, in some cases, have already won defining majorities within the Western …

Do People Get More Conservative With Age?

There’s a famous (but unattributable) quip that goes something like this: If you are not a liberal at 25, you have no heart. If you are not a conservative at 35, you have no brain. In Chapter 12 of Probably Overthinking It, I used data from the General Social Survey (GSS) to show that the quip is half right. Older people hold more conservative views. But as people get older, their views don’t become more conservative; on average, they become...

Baratunde Thurston & Blaise Agüera y Arcas: On Interdependence

In this conversation, Blaise Agüera y Arcas and Baratunde Thurston explored what a story of symbiosis and interdependence might teach us about living alongside AI. Agüera y Arcas began by calling individual human intelligence a myth: we’ve always been a collective intelligence, entwined with our technologies. He traced this back to symbiogenesis. Life has grown more complex not by splitting apart but by merging, as separate organisms fuse into increasingly complex new forms of life. These mergers speed up change by opening new possibilities. Thurston agreed that union is in our nature but framed the current technological acceleration as a speed problem. We need time and new stories to adjust because, as he reminded us, “when you invent the ship, you invent the shipwreck.” Caring for one another through acceleration must be our prime directive, he said. The two then turned to how we relate to AI. Responding to Joanna Bryson’s argument that robots should be our slaves, Thurston said the master is also in chains — owning another dehumanizes the owner. As relational beings, how we treat AI will shape how we treat each other. Thurston called for both an expansion and a humbling of how we define ourselves: “We’ve overdone independence,” he said, “interdependence makes us richer.” Agüera y Arcas agreed and pushed us to drop a zero-sum definition of human intelligence, where every AI advance diminishes humanity’s value. As technology advances, we trade some individual skills for new collective capabilities, Agüera y Arcas acknowledged. But over the long arc of history, he believes, that exchange pays off in collective flourishing. Thurston didn’t deny this, but he closed with an urgent question: who controls the loss of capabilities and agency?
