We're gonna abundance so much, you may even get tired of abundance. And you'll say, please, please, it's too much abundance. We can't take it anymore. Mr. Musk, it's too much, and I will say no it isn't, we have to keep abundance, we have to abundance more, we're gonna abundance more!
odd I don’t see any of the “abundance democrats” posting about the combined spaceflight / satellite constellation and telecommunications / AI company today, which is experiencing the largest IPO in human history — I would have thought they’d be excited!

From what I know right now, I think this Fable export control decision is the worst federal AI policy decision in history. I hope it stays the worst.

Solar is impressive. Mankind currently adds ~600GW per year (or about 120GW firm) by installing ~2.7m panels *every day*. In order for Valar Atomics to exceed this rate, we only need to install 13 of our reactors per day to match. And our goals are much more ambitious than 13.

Yes, America’s power grid is awesome 💪🏼 But speed to power and customer preferences matter too What if new customers would rather not deal with monopolies? Here’s the policy paper @Edison_Electric doesn’t want you to read cato.org/briefing-paper/case… Freedom is the American way 🇺🇸

✅Energy Milestone Achievement! Next stop: powering the nation. The @AntaresNuclear reactor at @INL achieved criticality, the first major hurdle in powering the United States with domestic nuclear energy. INL continues to lead the nation and the world in nuclear innovation and this breakthrough paves the way for the future of reliable baseload power.
🎉 WE HAVE CRITICALITY! 🎉 On June 4, 2026, at around 12:30 MDT, @AntaresNuclear’s Mark-0 microreactor achieved initial criticality at @INL. It is the first nuclear test reactor to go critical under @ENERGY’s Reactor Pilot Program. Congratulations to Antares on reaching this historic milestone!

AI is facing the same policy choice that defined the internet era. @AdamThierer, senior fellow at R Street Institute and a 30-year tech policy historian: "When I was growing up in the '70s, it was a big deal when we got a telephone that was a different color and had a longer cord. That was innovation back in the '70s." "Then the internet came along, we decided to have a firm firewall between that old era of regulated monopoly and the new world of digital technologies. We allowed them to be born free of government top-down control." "And we saw this flowering of entrepreneurialism and creativity and culture because of that policy choice." "Are we going to allow it to continue to be a technology of freedom? Or are we gonna bottle it all up and centralize?"

I still don’t know what to make of Brad. He starts by telling me he’s consulted “very experienced lawyers” and within minutes is repeatedly begging me to ask an LLM. Appeals to authority are always extremely strange when debating legislative text. But this is bonkers.

Every red-highlighted sentence in the below @americans4ri two-pager, which discusses @JayObernolte and @RepLoriTrahan's AI bill in red is either overbroad, misleading, partly false, or false. Full explanations in next post.

Brad is begging us to ask our LLMs. He asked his model whether federal law requires labs to scrub their data. That’s the procedural question, and it isn’t the one in dispute. A request. Give your LLM the following prompt: “Under U.S. federal law: (1) If child sexual abuse material is present in an AI lab’s training dataset, is the lab’s knowing possession of it already a crime under 18 U.S.C. § 2252A? (2) Can the willful blindness doctrine establish that knowledge for a lab that runs a web-scale scrape and chooses not to check? (3) Once a lab knows the material is in its dataset, is continued possession a crime? (4) Does that prohibition apply regardless of whether a state separately requires scrubbing?” The honest answer is yes to all four. Possession is possession. A training corpus on a lab’s servers is possessed by that lab, and knowingly possessing CSAM is already a federal crime.

Brad is going around claiming that preemption is coming for local rules on data centers, with Monterey Park held up as the example. This isn’t true, and the text is unambiguous. Sec 121 preempts only a law “specifically regulating the development of any artificial intelligence model.” The findings say the same thing. The stated purpose is to preempt “State regulation specifically targeting artificial intelligence model development.” The bill defines “development” as the acts of a developer: determining training objectives, training, fine-tuning, modifying a model’s weights, and evaluating before deployment whether it clears safety or capability thresholds. Building, powering, or zoning a data center appears nowhere in that definition. A company operating a data center and leases out compute is not a developer under the bill, because the definition requires both setting the training objectives and directing the training. On top of that, Sec 121(c)(1) expressly preserves “any State law or regulation of general applicability.” A data center moratorium is a land use rule. It applies to the building regardless of what runs inside, whether that is AI training, crypto mining, or ordinary cloud storage. Now look at the measure Brad uses. The ballot language prohibits data centers citywide to protect air quality, water, and public health, and to prevent spikes in electricity and water rates. It doesn’t mention AI model development anywhere. It’s about as clean an example of a generally applicable local land use law as exists, and nothing in this bill preempts it. The voters who passed it would not being overridden by anything in here. There’s one place a preemption argument might have footing. The word “specifically” is used but not defined. If a city wrote an ordinance that singled out data centers because they’re training AI, a developer would have an argument that the ordinance specifically regulates development. A neutral data center ban doesn’t get there. The general applicability carve-out and the developer definition both cut the other way. Monterey Park’s measure is neutral. It bans all data centers for environmental and infrastructure reasons. So this is the one example the argument cannot reach. This is the second time today this account has steered the public toward a reading of this preemption that the text does not support. The first was CSAM. Brad and ARI claim that scrubbing child sexual abuse material from training data a development-level mandate the bill would strip from states. But possessing that material is already a federal crime, which means no lab may lawfully hold it in a training set no matter what any state does or doesn’t require. A general criminal prohibition on that material is a law of general applicability, which is clearly left untouched. The protection they claim the bill removes is secured by federal criminal law that this bill does not touch. Both arguments are built the same way. Each one stretches “specifically regulating the development of an AI model” to cover something that sits outside it, and each one only holds up if you leave out the general applicability carve-out written into the same section. The CSAM version leaves it out. The data center version leaves it out and then points at Monterey Park, which the carve-out squarely protects. This is a pattern. This is an organization with lawyers. A general applicability carve-out is not buried, and it is not hard to understand. When a group steers the public toward reading a preemption clause to reach already-criminal conduct and a local land use vote, twice, while leaving out the one sentence in the text that answers both, the charitable explanation gets hard to hold. At that point the framing reads like an effort to be believed by people who have not opened the bill. There are real questions about this bill. But the argument has to start with what the text says. Read Section 121, all of it, and then we can have the real fight.

Go read 49 U.S.C. § 30103(b) (which preempts state car-safety standards) and then 49 U.S.C. §§ 44701 and 44704 (only the FAA certifies aircraft). Y’all just cited the two best examples of federal pre-market preemption. Thanks for the support, @americans4ri!
Countering AI harms happens at the pre-deployment level. You test cars before they're on the road, and planes before they take off. Here's why broad preemption of pre-deployment state laws fails. Two-pager: ari.us/wp-content/uploads/20…
