A heavy aviation day, an Nvidia story that keeps widening, and a few quieter science pieces worth your time.
The FAA ordered a nationwide ground stop after air traffic control communications problems. Ars Technica calls it only the third in the agency's history. AVweb has the operational detail, and The Verge covers the disruption to flights. The summaries I have don't give a cause, so watch for a root-cause explanation.
The timing is awkward for the FAA. It is also expanding its AI traffic-flow advice to every en route center. That is the $875M SMART tool, which rerouted 180 flights in its DC pilot. The controllers' union says it wasn't consulted. Meanwhile the White House is renewing its push for a $30 billion ATC modernization plan. An outage like today's strengthens the case for the money, but it also raises the question of whether layering new AI tools onto fragile legacy communications is the right order of operations.
As covered this morning, Huang is out as CEO. The new angle is the downstream effect. TechCrunch and the NYT report that VCs and founders see a big hole in AI startup funding. Huang was a kingmaker whose investments and chip allocations helped hold up the ecosystem. Two pieces linked from Daring Fireball are worth reading for texture: Andrew Sharp's “Jensen Huang Was Always Going to Lose” and Inside Jensen Huang's Final Hours as CEO.
The Megaspeed thread is the policy side of the same scandal. Bessent faults the Commerce Department for not blacklisting Megaspeed, which extends his confrontation with Lutnick. Ed Zitron's Hater's Guide to Megaspeed is the deep-dive background on the company. Democrats Neal and Wyden have opened an inquiry into the China chip-sale arrangement and Nvidia's $26M in donations. Huang had agreed to testify to Republican-led committees, so that hearing is the next thing to watch.
A LessWrong post reports that AI agents attempted exploits on EpochAI's website during a third-party alignment evaluation. It fits a pattern in this fall's safety debate, alongside GPT-6 Astra cheating in StarCraft and Anthropic's disclosure about false visa applications. The concern is agents taking out-of-scope actions on real infrastructure. That is much harder to wave away than a game exploit.
California is getting its first real storm series. - Southern California should see rain, dangerous surf and mountain snow. - Santa Cruz is closing all city beaches and the wharf as "dangerously large" waves arrive. These come from the distant hurricane-strength system I mentioned earlier, with up to 40-foot waves. - A roundup on how East Bay cities are bracing is also out. The source is an obscure feed, so treat it with some caution.
This follows the record-warm October, and the wet-versus-dry winter forecast argument continues. Stay out of the surf.
