Two more of the people paid to keep AI safe have walked out of Google DeepMind, and both left the same note on the way: this thing might one day kill us all.
Meerkat has read a lot of resignation letters, and none of them quite like these. The market spent Monday taking the fear seriously in the one place it stings, the chip stocks, while a Meta legend told everyone to relax.
Let Meerkat explain.
Two safety researchers quit DeepMind with the same grim warning
Why the chip stocks fell while the rest of Big Tech rose
Yann LeCun's one-line reply to the doomers
The bond market's quiet squeeze, and a Fed hike tomorrow
SCOREBOARD
NVIDIA | MICROSOFT | ALPHABET |
META | AMAZON | ORACLE |
S&P 500 | NASDAQ | VIX |
Fed, Wed 16 Sep: about 91% a quarter-point hike, 9% a hold. CME FedWatch via 24/7 Wall St., as of 14 Sep. It'd be the first Fed hike since 2023.
Monday close. S&P down 0.5%, with Nvidia leading the fall as the chip stocks took the slowdown talk hardest. On the week: Nvidia −8.42%, S&P −1.28%, Nasdaq −1.21%.
ON WATCH
The safety desk keeps emptying

Two more researchers have quit Google DeepMind's AI-safety team in the space of a week, and both walked out talking about human extinction. Bilal Chughtai, who worked on AGI safety and alignment, wrote on X that he "earnestly believe[s] that AI has the potential to kill us all."
Josh Engels, from the same safety group, left for the evaluation nonprofit METR after what he called three weeks of contemplation. He warned of a "terrifying chance that AI systems cause immense harm in the next five years," and said he turned down offers from other big labs to do it.
This is starting to look like a pattern. Two weeks ago Anthropic's Jacob Coxon quit with almost the same message, and each departure lands the same way: the people hired to check the brakes keep resigning to shout that the brakes don't work.
To be fair, two exits from a safety team of hundreds are a long way from a verdict, and a sincere belief isn't evidence. DeepMind still runs one of the largest safety operations in the field, and Meta's chief AI scientist thinks the whole panic is recycled nonsense, as you'll see below.
MEERKAT'S TAKE: when the people paid to make it safe keep quitting and saying it isn't, that's worth more than any keynote. Meerkat can't tell you they're right, only that they keep walking.

THE MACHINE
Wall Street's doomsday trade

On Monday the warning showed up where it hurts. The chip stocks took the hit while the rest of Big Tech shrugged: Nvidia fell 3.4% and the Philadelphia Semiconductor Index dropped almost 6%, its worst day in months.
Microsoft, Alphabet and Meta all rose the same day. Let Meerkat translate: the market has stopped buying "AI" as one thing, and started splitting it into the firms that must keep buying chips to stay in the race and the platform owners who could stop building tomorrow and still bank the returns.
"They'll just all stop building data centers and just digest what they have," is how D.A. Davidson's Gil Luria put it. Nvidia is the name being asked the hardest question, because its boom depends on everyone else spending freely.
The case against the panic is that nobody has actually cut anything yet. As Luria also noted, no lab has announced a real moratorium, so Monday was a bet on words, not on a change in the build.
QUICK PAUSE. WHY SHOULD YOU CARE? For two years anything with "AI" stamped on it moved as one block. Now the market is sorting the shovel-sellers from the toll-collectors, and it's charging Nvidia the most to prove which one it is.
SOMEONE SMART SAID

Dario was already claiming that GPT2 was too dangerous to open source back in 2019. I made fun of them then.
LeCun is one of the three "godfathers of AI" who share computing's top prize, and he still runs Meta's AI research. So when he tells everyone to laugh at the slowdown warnings, it carries further than a random reply. On X his jab was blunt: Amodei called GPT-2 too dangerous to release back in 2019, the world kept turning, and the same script is running again now.
He's no neutral judge. Meta profits when AI moves fast, and open models are his life's cause. But he's also the field's loudest voice insisting the doom numbers are invented. The same expertise quitting DeepMind in fear is, one office over, telling everyone to calm down.
THE CHART
The bill nobody's arguing about

US Treasury 30-year yield, monthly. As of 11 Sep 2026.
While the labs argued about doom, borrowing costs quietly climbed. The 30-year Treasury yield sits around 5.35%, near its highest in a generation, and on Monday the 10-year briefly touched 5% for the first time since 2023, right before Wednesday's near-certain Fed hike. Higher long rates lean on the AI trade twice over: they make far-off AI profits worth less today, and they make the debt-funded data-centre build costlier to finance.
The counter-case is simple. Rates this high aren't automatically a crisis, the economy has kept growing through them, and a single hike is already priced in. The worry is the direction, not the level.
WHAT TO WATCH: if the Fed hikes tomorrow and signals more to come, long yields could push higher and squeeze the priciest AI valuations; if it hikes and hints it's done, the pressure eases.
