C’est elle qui a jeté Fauci en pâture relayé ensuite par RFK et Musk…
Je vous le dis
Le RN au pouvoir ça sera ça.
On peut ne pas être content.
Vouloir du changement.
Mais le changement ça peut être en pire.
Les USA 🇺🇸 en sont le parfait exemple.
En pleine idiocratie.
Et ça nous pend au nez.
Car pardon mais les 3-4 élus RN qu’on ne cesse de voir qui tiennent la route face caméra c’est le vernis
On gratte un peu et on voit vite apparaître la rouille.

- unemployment: economists say there won't be mass unemployment due to AI. Don't listen to Dario, he is not an economist. Talk to your Stanford colleague @erikbryn
- inequality: that's a fiscal policy question, not an AI technology question. One can lament the growing inequalities in the US, but the solution is to reduce corruption not slow down AI (other countries are doing just fine, by the way). Inequality started growing in the US in the 1980s with Reagan. Nothing to do with AI (ask Erik).
- warfare: right now, the deployment of AI in drones is protecting liberal democracy in Europe against an authoritarian invader. Abandon at your own risk. I sure won't.
- loss of meaning: Aristotle lamented the loss of meaning due to the increased prevalence of writing. Antique marathoners lamented the loss of meaning due to horse riding. AI won't cause any more loss of meaning than fire, iron, agriculture, writing, horses, books, engines, cinema, calculators, TV, computers, or the internet.

In fact, AI has already enabled:
—a non-invasive blood test to assay the tumor microenvironment (optimizing the use of immunotherapy, never previously available)
— discovery of a 14-protein blood test to prevent lung cancer
— guided the selection of neoantigens for personalized vaccines, such as for cure of pancreatic cancer in refractory cases

"We Have to Stop Freaking Out About A.I." warns Nobel laureate Robert Shiller. Depressions, formerly called panics, are caused by self-fulfilling fears (the only thing we have to fear is fear itself), i.e., common knowledge about those very fears. https://t.co/eSQ0VW8Ckd

The dismantling of USAID has already ensued in roughly 600,000 deaths, about 400,000 of them children, in poor nations abroad, according to Boston University epidemiologist Brooke Nichols.

The toll is expected to rise as health infrastructure that became reliant on Western support deteriorates, resulting in deaths that may take months or years to register.

The Emperor Has No Clothes: Why the AI Infrastructure Buildout Math Doesn't Work

I have to give IBM CEO Arvind Krishna credit. He's saying what many of us in this industry have been thinking but haven't been willing to say out loud. The math just doesn't add up.

Here's what I'm seeing that's deeply troubling. We're in the middle of another mass hallucination. Just like the dot-com bubble, just like blockchain, just like the metaverse — everyone is convinced that building massive data centers will automatically create massive wealth.

But here's the thing about building infrastructure. You actually have to sell what's inside it.

Let's talk numbers. The planned data center buildout over the next 5-10 years is staggering. We're talking about commitments in the hundreds of gigawatts globally. The capital expenditure commitments are in the trillions. Yet when you look at the actual demand signals, not the projections, not the potential, but the actual consumption patterns, there's a massive gap. These AI companies are betting everything on demand that simply doesn't exist at the scale they're planning for.

Let me be direct. AI services are expensive. Enterprise adoption is slow. Consumer AI is still finding its footing. And the compute requirements being promised by the hyperscalers require a level of demand that would represent a fundamental shift in how businesses consume technology. That's a big ask.

I've seen this pattern before. The overbuilding. The belief that if you build it, they will come. The groupthink that turns critical analysis into heresy. The result is always the same. Companies are going to touch the stove. We're going to see massive write-downs. We're going to see pivots, shutdowns, and strategic reviews. We're going to see companies that spent years and billions trying to be the AI infrastructure leader become case studies in how not to read a market.

The IBM CEO is right. The math doesn't work. And unlike 1999, we don't have the excuse of we didn't know. We know exactly what's happening. We just don't want to believe it because the alternative, being a skeptic while everyone else is piling in, feels like career suicide. It's not. The ones who survive the next decade will be the ones who built for reality, not fantasy.

Wake up. The emperor has no clothes.

As reported by Futurism, Krishna laid out striking calculations: a 1 gigawatt data center costs roughly $80 billion today. If one company commits 20-30 gigawatts, that's $1.5 trillion in capital expenditure. The total commitments across the industry for chasing AGI are approximately 100 gigawatts, equaling $8 trillion. To break even, you'd need $800 billion in profit just to cover the interest. That's not investment. That's hoping.

🚨🚨🚨A standing ovation for the Washington Post, @wapo . 👏👏👏

You spent a full year investigating whether America's Director of National Intelligence, the woman with access to every classified secret this country has, was being directed by a cult leader who got busted for pyramid schemes in multiple countries.

And you held it until she resigned?

This same cult leader, Chris Butler, has his sect directly tied to QI Group (QNET), a Hong Kong-based company with operations across Asia, Africa, and the Middle East.

So the real question: Which countries now have access to our national intelligence? Which of our spy names are compromised?

And let's not forget, this is the same Tulsi Gabbard who used her position to do a coordinated hit job on Dr. Fauci, a man who spent his entire life saving Americans.

Imagine if this story dropped while she still had her hands on our nation's secrets.

Our press and mainstream media are failing us at every level.

Obama is, was, and always will be superior to the worst president in history, Donald Trump.

Obama got Iran to give up 98% of its enriched uranium, keep enrichment below 4%, and allow inspections to verify without starting a war, losing a service member, or having the Strait closed.

Trump started a war with Iran that caused the US inflation to rise so high that wage gains disappeared, and people fell further behind. 13 service members were killed. 43 aircraft were lost or damaged. 15 US bases took heavy damage. Trump surrendered in Versailles without gaining a single thing.

Obama inherited a rough economy during the Great Recession and got America moving in the right direction again.

Trump inherited an economy called "The envy of the world" and drove it into the ground.

Obama used the Situation Room to conduct a raid to take out Bin Laden.

Trump's administration used the Situation Room to discuss how to cover up his Epstein Files scandal.

Obama has 0 felony convictions.

Trump has 34 felony convictions.

Obama passed the most consequential healthcare legislation since Medicare and Medicaid were enacted.

Trump announced a decade ago that he would have a healthcare plan in two weeks, but has never released one.

The number of uninsured Americans decreased by over 18 million during Obama's presidency.

The number of uninsured Americans is projected to increase by 8 million during Trump's presidency due to major cuts enacted by Republicans.

Obama created the Consumer Financial Protection Bureau to protect consumers from predatory companies.

Trump continues to try to destroy the CFPB.

Obama was ranked 7th in the Presidential Greatness Project.

Trump was ranked dead last.

Anthony Fauci is an American hero who kept us protected from deadly viruses for decades. The people spreading lies about him are spreading Russian propaganda because they get paid to do so. They are the real traitors. Russia would love to know what we have in our biolabs so they can use that research to hurt Ukraine who is dominating them with drones.

Donald Trump will go down in history as the only US President to be outwitted by a single-celled organism.

They’ve arrested more people for touching the peeling paint at the Reflecting Pool than they’ve arrested from the Epstein files.

[James Tate @JamesTate121]

Step 1: Remove filters in Reflecting Pool because Obama put them in.
Step 2: Give your criminal neighbor who runs "Greenwater Services" a $20 million no-bid contract to paint the pool.
Step 3: Fill the pool with water from the Potomac River, the phosphates from which cause algae blooms.
Step 4: Freshly sealed pool and extreme heat result in a super scum event
Step 5: Direct National Park Service to dump hydrogen peroxide into the pool which causes the paint to peel.
Step 5: Deploy US National Guard to stop people from taking photos of the swamp as a perfect metaphor for the administration.
Step 6: Blame someone else.

[Dr Terry Simpson @drterrysimpson]

Fauci was a hero - he didn't kill millions, but he did save millions of lives. Highest paid? Hardly - he was a civil servant getting paid much less than had he gone into private practice. People like you who don't know science are a clear and present danger to society

[Richard Hanania @RichardHanania]

Absolutely insane revelations about Tulsi Gabbard.

Throughout her public life, she's been a puppet for a Hindu cult.

Washington Post got access to 25,000 pages of documents including directives from Tulsi Gabbard's cult leader telling her which policy positions to take and how to present herself throughout her career.

It matches her record in Congress. At one point, she was instructed to say "It’s not a ‘boohoo, I don’t get to go to the party’ situation, Wolf" during a CNN interview, and used that exact phrase. This is one of several examples of her taking direct orders about what to say on TV. They told her what to tweet about too.

The cult set up fake accounts to boost her on social media. Gabbard was aware, at one point telling them to add a photo to a profile.

An email records a phone call where she was yelled at, but Tulsi is reminded at the end that "we still love you."

This woman was always a freak, which is why she ended up in the MAGA coalition. Anti-vaxxers, criminals, racist, and a woman in a weird cult all end up as allies. Trumpism is Kakistocracy.
