Good morning. It's Sunday, March 22nd, 2026. Here's your tech and science briefing.

**Musk announces Terafab — a $20 billion chip fab powered by Optimus robots.** Elon Musk unveiled "Terafab" this weekend: a vertically integrated semiconductor manufacturing facility to be built near Austin, Texas, jointly operated by Tesla, SpaceX, and xAI. The stated goal is audacious — one terawatt of computing power per year, targeting chips for AI inference, robotics, and orbital data centers. The Austin Business Journal puts the price tag at $20 billion or more, with production targeted for 2027. What makes Terafab different from other chip fabs is the production method: Musk says Optimus humanoid robots will be heavily involved in building and operating the facility — robots making chips to build more robots, with xAI's models running the show. It's the most vertically integrated AI-hardware play since Apple moved to its own silicon, but at Musk scale.

**Russia's critical Baikonur launch pad is back online.** This morning, a Soyuz-2.1a rocket carrying the Progress MS-33 cargo spacecraft lifted off from the Baikonur Cosmodrome in Kazakhstan — the first launch from the site since a significant pad accident damaged it more than three months ago. That's not a routine milestone. Site 31/6 is the *only* Baikonur pad certified for the Soyuz rockets that carry crew capsules and cargo to the International Space Station. Its loss had put serious constraints on Russian ISS resupply operations. Progress MS-33 is carrying over 2,500 kilograms of food, fuel, and supplies for the station crew. The pad's return to service reopens the full cadence of Russian ISS logistics — important context as Artemis II sits on Pad 39B in Florida targeting an early April launch window.

**Anthropic vs. the Pentagon heads to court Tuesday.** Anthropic filed sworn declarations in a California federal court late Friday, pushing back hard on the Defense Department's claim that the company poses an "unacceptable risk to national security." The filings argue the government's case rests on technical misunderstandings and mischaracterizations of positions Anthropic never actually took during months of negotiations — and a newly surfaced court document reportedly shows the Pentagon told Anthropic the two sides were "nearly aligned," a week before the Trump administration publicly declared the relationship dead. A hearing is now scheduled for this coming Tuesday, March 24th, before Judge Rita Lin in San Francisco. How this plays out matters well beyond Anthropic: it's shaping the precedent for whether AI safety commitments can be weaponized as a procurement disqualifier.

**The DePIN and restaking sectors are in a sharp contraction.** A wave of crypto industry layoffs reported this week has a clear pattern: companies in decentralized physical infrastructure networks — DePIN — along with restaking protocols and layer-2 scaling projects, are cutting staff and in some cases shutting down entirely. Analysts quoted by Crypto News and CoinTurk point to the dual pressure of a broader crypto market downturn and the gravitational pull of AI — firms that can pivot to AI infrastructure are doing so, and those that can't are shrinking. For DePIN specifically, the thesis that decentralized wireless and compute networks could challenge centralized providers is running into the reality that enterprise AI spending is flowing almost entirely toward hyperscalers. Worth watching how established DePIN players with real network deployments navigate this reset.

That's your Sunday morning briefing. Stay curious, stay skeptical, and we'll be back tomorrow.
