The Extension Cord
NVIDIA CEO Jensen Huang called Elon Musk the day The Atlantic reported what the valley has been quietly confessing for months: Silicon Valley added twenty-five megawatts of data-center capacity last year — four hundred and eighty-four megawatts in total, all of it — while a single hyperscale training campus now wants more than that on its own. The call covered ERCOT’s dead week of 2021, Cybertruck panels that leave the truck at highway speed, nuclear legislation by tweet, the forty-nine thousand Lake Tahoe residents about to lose three quarters of their power, a record five-hundred-billion-dollar funding half, and Mars. The greatest business on Earth is now gated by the extension cord. Musk pitched the one that drives itself.
JENSEN: Elon. I just read The Atlantic piece. "Silicon Valley Has Lost Its Biggest Advantage." [pause] Silicon Valley added twenty-five megawatts of data center capacity in the last year. Total. All of Silicon Valley. Four hundred and eighty-four megawatts combined. That's — that's nothing. A single Blackwell rack draws more than that.
ELON: lol twenty five megawatts is basically a lamp
JENSEN: It is not basically a lamp, Elon. It's twenty-five megawatts. That's enough to power roughly eighteen thousand homes. The place that invented the future cannot power the future. And I sell the thing that needs the power! I am selling hot silicon to people who cannot plug it in! That's my business model now. Sell the GPU, hope for the outlet.
ELON: have you considered texas. i moved here. it's great. no state income tax and the grid only collapses sometimes
JENSEN: The Texas grid — ERCOT — that grid killed people in 2021. People froze to death in their homes. And you want to put AI training clusters on it.
ELON: that wasn't the grid's fault that was the weather. the grid is fine now. probably. i don't actually check
JENSEN: You don't check. You put the most advanced computing infrastructure in human history on a grid that you don't check on.
ELON: i have people for that
JENSEN: You have people for that. [pause] Do your people know that nearly half of all data centers planned for this year — twenty-twenty-six — have been delayed or cancelled because the grid can't handle them? Half, Elon. That's not a bottleneck. That's a eulogy.
ELON: ok but here's the plan. we mount GPUs on cybertrucks. mobile data centers. full self-hosting. each cybertruck has a starlink dish on top pulling data and a megapack underneath pushing compute. the cluster drives to wherever the electricity is. texas has cheap power at night? drive to texas. nevada has nuclear? drive to nevada. it's uber but for GPUs
JENSEN: That is — Elon, that is the single stupidest idea I have ever heard. And I worked at AMD in the nineties. We tried things at AMD. Bad things. Nothing this stupid. You want to put a hundred-million-dollar GPU cluster in the back of a truck whose steel panels detach at highway speeds?
ELON: the panels don't detach they "degrow." it's a feature
JENSEN: They DETACH, Elon. There are lawsuits. NHTSA opened an investigation. The thing you built to replace the truck falls apart faster than the truck it replaced.
ELON: anyway the real play is nuclear. i tweeted about it
JENSEN: You tweeted about nuclear.
ELON: yeah i said we should build a million small reactors and everyone agreed
JENSEN: Who agreed? You tweeted "nuclear is underrated" at two in the morning and three hundred thousand accounts with anime avatars liked it. That is not a regulatory approval. That is not a construction permit. That is not a connection to the grid.
ELON: it's a mandate Jensen. the people have spoken
JENSEN: The people have not spoken. The people in Lake Tahoe are about to lose seventy-five percent of their power because a data center moved in next door. Forty-nine thousand people, Elon. So that ChatGPT can answer "how to boil an egg" in point-three seconds instead of point-four. Those people have spoken, and they are saying: I would like my lights to work.
ELON: ok that's actually pretty funny. but hear me out. what if the data center and the town shared the power. like timesharing. during the day the humans get electricity. at night the GPUs get it. everyone wins
JENSEN: Humans need electricity at night, Elon. That's when they use lights. And heaters. And medical equipment.
ELON: minor edge cases. look the real problem is that silicon valley is in silicon valley. why are we still there. there's no power. there's no room. the rent is forty dollars a square foot for a building that can't keep the rain out. the last office building linked to the weWork guy literally flopped. that's a sign
JENSEN: The WeWork building flopping is a sign of many things, Elon, but not of what you think. And by the way — five hundred and ten billion dollars of venture funding poured into AI in the first half of this year. Five hundred and ten billion. Eighty-one percent of all venture capital on Earth. And the place where it's happening can't add enough megawatts to charge a phone.
ELON: so move everything to texas. or mars
JENSEN: We are not moving data centers to Mars.
ELON: not yet. but the power situation on mars is actually incredible. unlimited solar. thin atmosphere means no cooling problems. zero regulations. zero NIMBYs. zero grid
JENSEN: Zero grid! That's the problem, not the solution! You need a grid! GPUs need a grid! I cannot sell my Blackwell architecture to a planet with no electrical infrastructure! [pause] Elon, do you know what TSMC just did? They committed a hundred and sixty-five billion dollars to Arizona. Five new fabs in the desert. Because at least the desert has the Palo Verde nuclear plant.
ELON: oh yeah palo verde. biggest nuclear plant in the country. like twenty gigawatts
JENSEN: Three point three gigawatts. Not twenty.
ELON: close enough
JENSEN: It is not close enough! It's off by a factor of six! This is exactly what I'm talking about! You hear a number, you multiply it by six, you tweet it, and then a data center gets built based on your math and they're surprised when the extension cord catches fire!
ELON: that only happened once
JENSEN: It happened twice! [long pause] Elon. I am going to sell ten million GPUs next year. Every single one needs to plug into something. The greatest business in the world — the business that prints money, that determines the future of civilization, that decides who wins the next century — is now limited by an extension cord. The extension cord is the platform, Elon. The extension cord is the operating system. And nobody has one.
ELON: so is that a yes on the cybertruck quote
JENSEN: Goodnight, Elon.
ELON: it comes with free fsd btw. the data center drives itself to meetings. think about it
The facts underneath
The piece underneath the call is real: The Atlantic, “Silicon Valley Has Lost Its Biggest Advantage,” published July 18, 2026 — this episode’s date — on the data-center age turning tech companies into heavy industry. The numbers Huang reads off are real too: Chicago Fed tabulations put Silicon Valley at 484 megawatts of data-center capacity, with 25 megawatts added in the last year.
The squeeze is real. Sightline Climate estimates 30 to 50 percent of the data-center projects planned for 2026 face delay or cancellation, power being the binding constraint — a figure SemiAnalysis spent June arguing down in scale, not in kind. Tesla recalled over 46,000 Cybertrucks in March 2025 (NHTSA recall 25V-170) because the stainless cant-rail trim can detach at speed. In May, NV Energy told roughly 49,000 Lake Tahoe–area customers it may redirect their power toward data-center load — cuts reported at up to 75 percent. And ERCOT’s February 2021 freeze killed at least 246 people by the state’s count, with excess-mortality estimates running higher.
The money and the fabs are real. Crunchbase logged a record $510 billion of global venture funding in the first half of 2026, with frontier AI the center of gravity — OpenAI and Anthropic alone took $217 billion, 43 percent of all startup funding. TSMC’s Arizona build-out reached $165 billion in March 2025 — additional fabs plus two advanced-packaging plants and an R&D center — in the desert next to Palo Verde, the largest nuclear plant in the United States at roughly 3,900 megawatts. (Musk’s twenty gigawatts were not close enough, either.)
