"To build a larger and more capable fleet by 2030, the Navy should double down on investing in, fielding, and sustaining smaller attritable autonomous systems," writes PWH Faculty Director @mchorowitz in @WarOnTheRocks. Read more: warontherocks.com/the-navy-needs…

Is the US adopting military AI too fast? Michael Horowitz (@mchorowitz) argues the Pentagon is actually moving too slowly. He contends it is time to "hit the accelerator" on scaling proven AI.

Especially thrilled to do this work w two great @Penn alums! cc @PennSAS @perryworldhouse

West Point cadets are less likely to make automation bias errors w military AI adoption than the general public! Shows opportunities from AI + that training matters! Thx @DefenseOne & @DefTechPat for covering my research w @Lauren_A_Kahn & Laura Samotin defenseone.com/technology/202…

Super excited about this podcast on the AI/nuclear nexus - what to be worried about v what's overhyped!

CFR Experts Jessica Brandt, @mchorowitz, and @ChrisRMcGuire assess the new DeepSeek model and consider what it could mean for the U.S.-Chinese AI race: on.cfr.org/3QOC7yC

PWH Faculty Director @mchorowitz is quoted in this @NBCNews piece on the Pentagon's new deal with Google, explaining "to use Google’s AI models for classified purposes illustrates the growing importance of AI for U.S. national security." Read more: nbcnews.com/tech/tech-news…

Check out ⬇️ my thoughts on the newest DeepSeek release and what it means for AI adoption beyond the frontier. Short answer is that it's an adoption competition!

@deanwball @carlfranzen Congrats!

I have news to share: I am writing a book, currently untitled, set to be published by Penguin Press next year. I began my public writing career with the thesis that AI and related technologies will both necessitate and enable major changes to the institutional configuration of Western society. I believe it is possible for individual liberty, dignity, and property to survive the coming transformation, but that their survival will take serious collective effort. This book is a contribution to that effort. It is an attempt to describe a positive vision for the future of the American republic in particular, and all ordered liberty worldwide. But it will simultaneously be a diagnosis of a crisis: open societies have drifted from the principles they once embodied, and those principles must be re-imagined for modern ears if we are to embody them in the future. This will therefore be a work of political theory just as much it is an "AI book." There is not much more I can say about the project (yet), other than that it is, by far, the most ambitious work I have ever undertaken. My research and writing will not replace regular writing on Hyperdimensional, but the cadence of publications is likely to remain lower than it once was. I anticipate writing essays every 2-3 weeks for the foreseeable future. I expect my output to shift a bit more toward mini-essays posted on X, which is a format I have been using more anyway. I am immensely grateful for my readers' support over these last two years. Thank you to everyone who has taken the time to read my work, and to the countless people who have lent me a hand along the way. More to come soon.

“This category of lower-cost precision strike just didn't exist at the time that most American air defenses were developed,” explains @mchorowitz to the @nytimes in a piece about the drone technology being used in Iran. Read here: nytimes.com/interactive/20…

“This is the time where danger lights should be flashing for a great power like the United States, if we take history as a guide," PWH Faculty Director @mchorowitz explains in a @nytimes piece by @dwallacewells. Read here: nytimes.com/2026/04/15/opi…

Not all drones are created equal. In a new piece for @ConversationUS, @LaurenAKahn and I explain one part of the era of precise mass, the one-way attack drone category used as artillery for short-ranges and as missiles for longer-ranges, including by Iran theconversation.com/one-way-attack…

@MaloneySuzanne @NYT @akcronin @paul_scharre @JackieGSchneid Thank you!

Great @NYT discussion featuring @mchorowitz @akcronin @paul_scharre @JackieGSchneid + more on what Iran means for the future of warfare nytimes.com/2026/04/15/opi…

Does AI make the battlefield safer or more unpredictable? @mchorowitz of @perryworldhouse argues that AI systems offer more reliability when properly tested and validated. @techladylaura of @ICRC points to a critical concern: under the law, weapons must have predictable effects. If AI behaves in ways that can’t be anticipated, it's more difficult to protect civilians and plan responsibly.

In a video for @NewsHour, PWH Faculty Director @mchorowitz shares insight on the LUCAS drones being used in Iran. Watch here: youtube.com/watch?v=AMvy7d…

It was so fun to do this debate on AI and weapon systems!

Happening tomorrow! Join us at "Algorithmic Warfare in Iran and Beyond" at 10am PST/1pm EST. I'll be joined by the fantastic @jessicadorsey, @mchorowitz, and @Ritwik_G. This is a Zoom webinar. Please register using the link below.

So here is what I’m tracking for immediate to near-term @INDOPACOM impact of Iran ops: - WaPo reporting -800 TLAMs used (how far below requirements are we now? how long to replace?) - Timing of Japan’s TLAM buy is in doubt (after years of pushing for them to buy strike) - THAAD interceptors moved from Korea - Japan Marines shifted to Gulf (temporary) - Burning up medium to long-term CVN deployment readiness/availability - Bonus - whatever happened to upgrading U.S. Forces Japan to a joint force headquarters? What am I missing? What’s still to come? (More strategic assets like the E-3 destroyed?)

Important point here about trade-offs in international law with regards to emerging technologies!
