Today's thread is who sets the terms for AI's foundations. A federal court sent a lawsuit over the power plant behind one of xAI's data centers forward, and California voters decide on November 3 on an environmental-review measure that critics say could reach data centers.

From mathematics came a proposal to rebuild how research is judged and how people are hired, in response to a wave of AI-written papers.

Federal judge denies xAI's bid to dismiss the NAACP's Clean Air Act suit over its turbine power plant

A federal court in northern Mississippi on October 30 denied a motion by xAI to dismiss the NAACP's Clean Air Act lawsuit against the company.

The NAACP and its Mississippi State Conference sued in April, saying xAI and its wholly owned subsidiary MZX Tech built and operated a gas-fired power plant in Southaven, Mississippi, without permits. The plant supplies power to Colossus 2, the data center xAI operates in Memphis, Tennessee.

According to the complaint, the turbines were installed between August and December 2025, and as of April 7, 2026 there were at least 27 of them, with a combined generating capacity of at least 495 megawatts. The complaint says the companies applied for none of the air permits required before construction and operation.

xAI argued that the plaintiffs lacked standing to sue, that the turbines were mobile and exempt from state permits, and that the Clean Air Act's citizen-suit provision is unconstitutional. Judge Debra M. Brown rejected all three arguments.

Mississippi's environmental regulator had told xAI in July 2025 that it considered the turbines mobile and temporary and therefore exempt. The judge found that the plant's turbines are "stationary combustion turbines" under the federal standard. Earlier in October, the same court denied a similar motion to dismiss from the Department of Justice.

Mathematician Frank Calegari says mathematics has changed and proposes new rules for credit and hiring

In a guest post on Terence Tao's blog on November 1, mathematician Frank Calegari urged his field to change how it evaluates work in the age of AI.

Calegari calls OpenAI's October 6 release of more than 700 research papers a watershed in the history of mathematics. He also says the papers are atrociously written, violate the community's expectations of attribution, and in some cases are wrong. Mathematicians, he argues, should spend their effort where they have control: hiring, publishing and training students.

On evaluation, he proposes treating all work as if it were AI-assisted. Credit would shift from the result itself to the author's account of why the mathematics is interesting, what questions it raises and how it connects to the wider subject. Someone who chooses a worthwhile problem, obtains a proof with AI, understands it thoroughly and builds new questions from it would earn substantial credit.

On hiring, he wants personal conversation to count for more than a paper file, with interviews for postdoc and graduate positions as well as faculty jobs. He asks journals to demand much more in writing, ideas and exposition, and suggests leaving journals that cannot adapt.

For graduate education, he calls for more breadth across mathematics while keeping technical training. He also asks mathematicians to take more ownership of the results AI produces.

California's Prop 45 could open a fast track for data centers, environmental lawyers warn

Proposition 45, on California's November 3 ballot, could give data center developers a way to speed through environmental review, The Verge reported.

The initiative creates new review procedures under the California Environmental Quality Act (CEQA) for projects it defines as "essential," including housing, clean energy, water and transportation. Agencies would have 365 business days from a complete application to finish the environmental impact report, and court challenges would have to be resolved within 270 days, appeals included. Public comment on a draft report would run 45 days.

According to the state's Legislative Analyst's Office, applicants could choose between the new procedures and the existing ones. A court that finds a CEQA flaw could halt only the affected part of a project.

The dispute centers on the measure's "essential broadband internet access project" category. The text defines it as a project providing mass-market retail service that can exchange data with all or substantially all internet endpoints, including capabilities that enable the operation of that service.

An attorney at the environmental law nonprofit Earthjustice and a UC Davis law professor emeritus, among others, say data centers could fit that definition. An attorney supporting the measure argues that data centers fall outside it. The NAACP's California/Hawaii State Conference backs Prop 45.
