Walter Benjamin’s 1935 essay, read in full from the Harry Zohn translation in Illuminations, with his endnotes. Benjamin asks what happens to a work of art once it can be copied without limit: what he calls its aura, its unique presence in time and place, withers, and art loses its footing in ritual. Photography and above all film become the test case, from the screen actor performing for a machine to the audience that judges like an examiner while barely paying attention. He closes on the politics of the 1930s: Fascism’s aestheticizing of war, and the response he saw from the other side.

Two anonymous doctors, one a psychiatry resident inside the NHS and the other a senior physician who trained in the same years as Adam Kay, argue their way through This Is Going To Hurt, Kay’s bestselling diary of life as a junior doctor. Finalist number nine in the 2026 Astral Codex Ten book review contest. One reviewer reads the book as a clinical case study hiding in plain sight; the other thinks the author is less sympathetic than his fans allow. Along the way: how the NHS bargain was struck and how it frayed, what a registrar really carries at three in the morning, the misogyny charge, the martyr complex, and why a very funny book changed so little.

One year after If Anyone Builds It, Everyone Dies was published, Eliezer Yudkowsky, Nate Soares, and Duncan Sabien revisit the book’s six core claims and its fictional scenario against the events of the past year, and ask where things stand now that the world is finally paying attention.
* 00:00 - Introduction
* 01:16 - Year in Review
* 03:36 - Claims
* 03:46 - One. Artificial superintelligence (ASI) will be created, and likely before too long
* 05:06 - Two. Modern AIs are black boxes
* 05:31 - Three. Powerful AI will behave as if it is pursuing goals
* 06:36 - Four. With current techniques, we can’t reliably get AI to pursue the goals we want it to
* 08:59 - Five. By default, an ASI will have motives that are harmful to us
* 10:04 - Six. Humanity would not be able to defend itself against a rogue ASI
* 11:11 - Part Two
* 13:32 - Part Three
* 14:50 - The View From September 2026

Sayash Kapoor and Arvind Narayanan examine recent AI loss-of-control incidents and the divide between AI safety and cybersecurity. A detailed exploration of control, cyberdefense, and how their AI as Normal Technology framework is evolving.
* 00:00 - Introduction
* 08:59 - Table of contents
* 10:45 - Part 1: We can get better at AI control through technical and policy interventions
* 15:02 - Alignment is helpful but not sufficient for preventing safety incidents
* 18:29 - OpenAI did not use known control interventions that would have prevented the incident
* 22:07 - Existing organizational governance norms would have prevented the incident
* 25:27 - Why has the AI community under-invested in control?
* 32:14 - Will control keep pace with AI capabilities?
* 36:40 - AI control should become a job (and a part of every job), just like cybersecurity
* 42:02 - AI policy can incentivize AI control
* 48:28 - Part 2: There is great uncertainty about how AI will impact cyberrisk. But what we need to do regardless is relatively clear
* 50:05 - The specific threat that is urgent is cyberrisk
* 54:24 - How will autonomous cyber capabilities and open-weight models affect the attacker-defender balance?
* 56:33 - To understand what open-weight models mean for the future of cybercriminal activity, we need to understand the past correctly
* 58:49 - The majority of cybercriminals are surprisingly low-tech, and the barrier is monetization, not exploitation
* 01:00:51 - So, how much will AI help cybercriminals?
* 01:03:03 - Are we about to see harmful autonomous agents?
* 01:06:49 - Why the Morris worm is a good analogy for what might be about to happen
* 01:08:45 - What the future of cyberdefense might look like: the roles of people and defensive AI
* 01:10:15 - What are the gaps in the state of cyberdefense against AI?
* 01:15:32 - Part 3: What AI as Normal Technology got wrong — and right — about AI safety
* 01:17:51 - Do risks arise from development or deployment?
* 01:18:54 - How should we deal with rogue agents?
* 01:19:33 - The continuity hypothesis
* 01:22:50 - Jaggedness and risk-specific defenses
* 01:24:29 - Is AI safety on track?
* 01:26:07 - Conclusion
