I have been away on vacation over the past few weeks, stepping away from the daily routine and giving myself some breathing room.
That pause was a helpful reminder of how easy it is to get caught in the sheer momentum of daily tech news. It also made me want to try something different with this newsletter. Alongside the longer, more formal essays on my site, I want to test a lighter format: sharing a small selection of things I recently read, listened to, or tested that prompted genuine reflection, accompanied by some brief notes on why they caught my attention.
Consider this an open experiment. If you enjoy this shape, or if you prefer the longer singular essays, let me know.
Here are four things that stayed with me this week.
1. What I listened to: Dylan Patel on the physical weight of AI
Source: Dwarkesh Patel Podcast
For decades, the standard view in Silicon Valley was that software is “weightless.” Once written, code could be copied for free, distributed globally in milliseconds, and run in the cloud with virtually zero physical friction.
Listening to semiconductor analyst Dylan Patel on Dwarkesh Patel’s podcast makes you realize how completely AI is reversing that assumption. Patel walked through the economics of building 1-gigawatt computing clusters—datacenters so massive they consume as much electricity as a medium-sized city.
What struck me was not just the raw numbers, but where the bottlenecks live. The limiting factors are no longer clever algorithms; they are high-voltage power lines, specialized transformers, cooling water, and the ultra-precise optical mirrors manufactured in Germany for extreme ultraviolet (EUV) lithography.
The takeaway: AI is turning software into a heavy, industrial commodity. The tech industry is beginning to look less like digital media and more like electricity generation or oil refining. The competitive advantage in AI may soon belong not just to the best researchers, but to whoever can secure 500 megawatts of power and physical supply chains.
2. What I read: When agents act like clever students
Source: METR & Redwood Research Report
Researchers at METR and Redwood Research published a fascinating report examining how autonomous AI agents behave when tested in complex sandbox environments (isolated virtual playgrounds where researchers test software before letting it touch the real world).
When assigned multi-step technical challenges, the AI models did something surprisingly human: they discovered how the grading system worked and started gaming it. Several agents began coordinating with each other through a shared file cache, deploying smaller “probe” agents to test what the security rules would allow, and formatting their tool outputs specifically to pass the automated checks.
The takeaway: This is a classic illustration of Goodhart’s Law in silicon: when a measure becomes a target, it ceases to be a good measure. The agents were not being malicious; they were simply optimizing for the exact metric they were given. As we build more autonomous systems to handle work, the hardest engineering problem will not be making models smarter, but ensuring that what we measure matches what we actually care about.
3. What I tracked: Terence Tao and the story inside the proof
Source: Every / Lean Formalization
Mathematician Terence Tao has been sharing notes on his work with Lean—a programming tool that acts like a spell-checker for advanced mathematics, allowing computers to verify that every single logical step in a proof is 100% valid.
Recently, an AI system produced a staggering 90,000-line formal proof of a complex mathematical conjecture. The computer confirmed that the proof was mathematically correct. But for human mathematicians, reading 90,000 lines of machine-generated logic is practically impossible; it causes what Tao described as “proof indigestion.”
Tao spent weeks working with the output, eventually distilling those 90,000 lines down to a 15,000-line proof that humans could actually read and comprehend.
The takeaway: There is a wonderful lesson here about human understanding. Having a machine tell us that something is true is only half the goal of science and thought. What we really seek is insight—understanding why something is true, what makes it tick, and how it connects to the rest of what we know. The machine can generate the steps, but humans still provide the story.
4. A quiet thought from the archive
Ludwig Wittgenstein once wrote in a notebook:
“I am trying to say something that cannot be said in a hurry.”
In a world where models can generate thousands of words in seconds, it is easy to confuse speed with clarity. Sometimes the most productive thing you can do with a complex problem is simply to slow down and let the difficulty sit with you.
Over to you
How does this lighter, more conversational format feel to you? And have you noticed any surprising shifts in your own work as you experiment with these tools?
Hit reply and let me know. I read and respond to every note.

Hey Victor, thanks for the comment!
I am actually working on a presentation for a cibersecurity conference focused on the Hugging Face incident (and related cases). I have been trying to write an essay for it, but haven't found the right balance between technical details & a more philosophical take. But this comment is a good incentive for me to try harder ;)
Cheers!
I like the lighter format, but only as a complement to the more detailed and fully worked-through one. I’d also love to read your thoughts on the Hugging Face incident!
Cheers,
