Nvidia just admitted that "AI efficiency" is a LIE.
Every major tech company is doing the same thing right now:
Firing humans and replacing them with AI to "cut costs." 92,000 tech workers laid off in 2026 so far.
Every single earnings call sounds the same: "AI is driving efficiency."
But the VP of Applied Deep Learning at Nvidia, the company that literally SELLS the AI infrastructure, just told Axios:
"For my team, the cost of compute is far beyond the costs of the employees."
The man whose entire job is making AI work admitted that AI costs his company MORE than the humans it's supposed to replace. And he doesn't work at some struggling startup. We're talking about the most valuable company on Earth.
An MIT study backs this up too:
Researchers analyzed whether AI could actually replace human workers at a competitive cost and found that AI automation only makes financial sense in 23% of jobs. In the other 77%, humans are still cheaper.
So companies are firing cheap labor and replacing it with expensive labor, then telling shareholders it's "innovation."
But it gets even WORSE...
Uber just revealed that they burned through their ENTIRE 2026 AI budget in 4 months.
Their CTO said: "I'm back to the drawing board because the budget I thought I would need is blown away already."
What happened is that Uber gave their engineers access to AI coding tools and encouraged them to use them as much as possible. They even built internal leaderboards ranking engineers by how many AI tokens they consumed, basically gamifying their own budget crisis without realizing it.
By March, 95% of Uber's engineers were using AI tools monthly. 70% of all committed code was coming from AI. Monthly API costs per engineer hit $500 to $2,000.
One software engineer in Stockholm told the New York Times: "I probably spend more than my salary on Claude."
A human being now costs LESS than the AI tool they use to do their job.
And Uber isn't some edge case. Big Tech has announced $740 billion in AI capital expenditures this year alone, up 69% from 2025, according to Morgan Stanley.
Meanwhile the Yale Budget Lab says there is NO widespread data showing AI is actually displacing jobs or improving productivity at scale.
So follow the money:
Companies fire humans
↓
Stock goes up because "AI efficiency"
↓
Those same companies spend MORE on AI than they saved on salaries
↓
That money flows to Nvidia, Anthropic, OpenAI, and Microsoft
↓
Those companies use the revenue to justify their own insane valuations
↓
Everyone books growth
↓
But nobody's actually saving money
McKinsey projects total AI spending will hit $5.2 TRILLION by 2030.
The biggest wealth transfer in modern history is happening right now, and it's not from workers to companies. It's from companies to AI infrastructure providers.
Every dollar "saved" on layoffs is being spent twice over on compute, tokens, and data centers.
Nvidia posted $31.9 billion in profit last quarter. And somebody is paying that bill - the same companies telling their employees that AI made them "redundant."
The entire narrative is a shell game:
CEOs get to announce layoffs, Wall Street rewards them with a stock bump, and then the real cost shows up three months later when the AI budget explodes and nobody connects the two events.
What's your take on this?
Ha muerto Pepe Mujica.Esta vez sí, a los 89 años, decidió irse.
No lo logró la dictadura, ni las balas, ni la oscuridad de un pozo.
Lo venció el tiempo.
Nos deja el presidente más pobre, el más sabio, el más humano.
Una leyenda del sur que ya es del mundo
One of the most tedious (but critical tasks) for software development teams is updating foundational software. It’s not new feature work, and it doesn’t feel like you’re moving the experience forward. As a result, this work is either dreaded or put off for more exciting work—or both.
Amazon Q, our GenAI assistant for software development, is trying to bring some light to this heaviness. We have a new code transformation capability, and here’s what we found when we integrated it into our internal systems and applied it to our needed Java upgrades:
- The average time to upgrade an application to Java 17 plummeted from what’s typically 50 developer-days to just a few hours. We estimate this has saved us the equivalent of 4,500 developer-years of work (yes, that number is crazy but, real).
- In under six months, we've been able to upgrade more than 50% of our production Java systems to modernized Java versions at a fraction of the usual time and effort. And, our developers shipped 79% of the auto-generated code reviews without any additional changes.
- The benefits go beyond how much effort we’ve saved developers. The upgrades have enhanced security and reduced infrastructure costs, providing an estimated $260M in annualized efficiency gains.
This is a great example of how large-scale enterprises can gain significant efficiencies in foundational software hygiene work by leveraging Amazon Q. It’s been a game changer for us, and not only do our Amazon teams plan to use this transformation capability more, but our Q team plans to add more transformations for developers to leverage.
We've passed the tipping point in AI video.
The quality is now good enough that you can use it to tell real stories.

Entre 1939 y 1951, España se vio sumida en un periodo de escasez y miseria sin precedentes como consecuencia de la Guerra Civil y el bloqueo internacional.
Solo hubo un país que ayudó a España a salir del hambre y ser normalizada internacionalmente: Argentina 🇦🇷.

Poner el mundo del derecho es anteponer la ecología a la economía, es anteponer el ciclo del agua al negocio del agua, las personas al dinero, la naturaleza a la codicia.
