Peter Singer — Moral Truths and Moral Secrets

This is the second episode in a multi-part series called 'Compute in Australia'. Series announcement here. More episodes to follow over the coming month.

[Recorded 24 August 2026.]

Janet Egan is Senior Fellow and Deputy Director of the Technology and National Security Program at the Center for a New American Security in Washington, DC. Her research focuses on the national security implications of artificial intelligence. She was previously the inaugural director of policy in Australia's Office of Supply Chain Resilience.

I caught up with Janet while she was home in Australia to stress-test the strategic case for building a large compute industry here. We discuss why training compute gives Australia more leverage than inference compute, whether hosting compute could also give us influence over AI safety, why copyright is a red line for the AI companies, and why Australia's window to act is "a month or months, rather than a year".

The Geostrategic Case for Compute in Australia — Janet Egan [Compute Series]

This is the first episode in a multi-part series called 'Compute in Australia'. Series announcement here. More episodes to follow over the coming month.

[Recorded 7 August 2026.]

Dr Andrew Charlton MP is an Australian economist, entrepreneur and politician. As Cabinet Secretary and Australia's Assistant Minister for Science, Technology and the Digital Economy, he is one of the key leaders shaping the Australian government's AI strategy.

Andrew shares his internal model for how AI plays out economically and what a middle power like Australia should do about it. We discuss whether data centres will yield large economic rents, the geostrategic case for a compute industry, and how the government plans to use compute to climb the stack to "sovereign AI".
