Thanks to Harvard editors for helping publish (and improve) our work on 007, one of the most fascinating intellectual property stories of the 20th Century. Even if you're not usually into reading legal scholarship, this is an approachable, fun piece! 👇 journals.law.harvard.edu/jsel/wp-conten…

I want to talk about some good news in the Big Beautiful Bill, since the usual chorus of people is busy whining and worrying rather than discussing policy. First, two provocative framing statements: - Countries reporting they're developing basic fission weapons today is the…

Wow!! New version of Gemini (2.5 Pro w interim upgrades, deep res mode) notices a very tough subtlety in this libertarian argument (that it may be better to concede Lopez was wrongly decided than to continue to bask in its limitations on the Commerce Clause thirty years later).

Hey @ChicagoMayor: Cop pensions aren't the problem, teacher pensions aren't the problem; Art. XIII, Sec. 5 of the Illinois Constitution is the problem. It prevents a much-needed Chicago bankruptcy from being a viable route to municipal financial reset. chalkbeat.org/chicago/2025/0…

I am saddened to see the availability of firearms parts in 3D printer databases on the decline after several years of gunsmithing maker innovation in this area. America has a storied, important history of amateur gunsmithing and firearm assembly. In a forthcoming piece of…

I had an unusual Sunday convo with @Google's Gemini #AI this morning. 🤖🧠 The problem is I bring up two patents Google is infringing. 📘📘 Its solution? It claims Google controls the patents. 😐👎 @openai @tylercowen @alexroy144 Receipts link below. g.co/gemini/share/8…

I rarely post travel/food/etc. stuff anymore, but our Saturday night at @dtownboston (Sushi @ Temple Records) was truly remarkable. The quality of fish downstairs, quality of service upstairs (bar) and downstairs (restaurant), and overall quality of the experience? All 10/10.

I enjoyed @EconTalker's conversation with Mike Munger even more than the typical episode of EconTalk. Russ and Mike correctly identify that our system is not only remarkable because it functions without a central plan (which is itself a key insight in understanding the…

A free piece of advice for students looking for natural experiments: we look way too often to the legislative branch and too infrequently to the judicial branch to find them. I'll give you one example, but there are many more. Just over two years ago (on 6/29/23), Chief Justice…

As many of you know, I've been working on a long-form (30,000 words) law-and-policy piece on what the "Chicago School" viewpoint means in a modern world of YIMBYism, cryptocurrencies, and 3D-printed firearms. Thanks to those who've voiced an interest. In the meantime, however:…

I don't pretend to understand all the nuances of the Mamdani race debate, and I would argue to do so is impossible since it's an eye-of-the-beholder issue to at least some extent. That said, I did live in Uganda for several years and I think people underappreciate that history.…

I began working on this research in 2024 and many colleagues told me not to waste time writing research about the Iranian weapons program. Nobody was interested, it won't be relevant, Iran will develop technology in secret forever... four of your Israeli friends might read it.…

I'm not the kind of guy you'd expect to be surprised by a securities law prosecution. A chunk of the course I created at @NorthwesternU @NorthwesternLaw (Pritzker School of Law) is regulatory compliance in #securities markets. I taught seminars on these topics at @Stanford and…

I'm proud to serve on CGCI's Council, a collection of subject matter experts, entrepreneurs, inventors, academics, and retired military personnel exploring ways to invest in a defense-aligned, America-and-allies-first portfolio of exciting opportunities. linkedin.com/pulse/just-one…

It is unfortunate the GOP's "big bill" team was able to find 60 votes on other measures but could not find support for the NFA amendment portion of the legislation, needed revisions to an anachronistic rule set drafted by Rep. Doughton (D-NC) when Al Capone was 35 years old...
