LatAm Tech Weekly
#244: AI and Marathons, Kimi K3, deals of the week... and much more!
Weekly writing about what is happening in LatAm tech. By day, I am part of the corporate development team at Itau Unibanco. By night, I am reading and learning about technology in general (now, with a focus on AI). During the weekends, I’m writing the LatAm Tech Weekly. And obviously, always running!

Happy Sunday!
First things first: I’m off on long-awaited vacation!! Ten days off — or, well, “off.” If you’re an avid reader, you already know how this goes: I swear I’ll skip an edition, and then inspiration strikes me mid-vacation and I end up writing anyway. So — let’s see what this trip has in store... But without further ado, let’s dig in!

AI Won’t Replace the Marathoners
There is a moment in every marathon — usually somewhere around kilometer 30 — when the race stops being about talent or training. Your legs are heavy, the glamour is gone, and whatever carried you through the first 30km simply stops working. What gets you to the finish line is not a breakthrough — it is everything you did in the boring, unglamorous long runs that nobody saw.
I’ve been thinking about that moment a lot lately — because I think AI just hit its kilometer 30 (and obviously because I am training for my third marathon this year - below a picture of my latest 24km long run!)
I read two pieces this week that when read together, make the case better than either does alone. The first is David Brooks’ essay in The Atlantic, “The People Who Will Thrive in the AI Age” (June 2026). The second is the Work AI Index 2026 — a survey of 6,000 knowledge workers by Glean’s Work AI Institute, dissected at length on The AI Daily Brief (the podcast many of you know I listen to daily). The pieces are very different, but they arrive at the same place.
Volition is the new scarcity
Brooks’ core argument fits in seven words: when intelligence is plentiful, volition is valuable.
But before he gets to volition, he draws a map — and the map deserves a pause, because the entire essay rests on it. What separates people in an AI-saturated world, Brooks argues, is not intelligence. It is their relationship to mental effort. And on that spectrum, he sees three archetypes.
At one end sit the **cognitive misers** — the people who find thinking hard genuinely unpleasant and take any opportunity not to do it. For them, AI is less a tool than a permission slip: a machine that thinks so they no longer have to. They outsource judgment happily, accept the first output, and move on with their lives.
At the other end are the people psychologists describe as having a **high need for cognition** — the ones energized by hard problems, who play difficult games and read dense books for fun, who treat AI as a sparring partner rather than a crutch. Brooks gives them a name that, I confess, I personally related: **mental marathoners**. People who insist on running the mental marathon the way some of us insist on running 42km even though the car exists. His bet is that this group will actively resist handing over the thinking — not out of technophobia, but because they want their work to remain original, personal, theirs. They use AI to expand their agency, not replace it.
And in the middle sits everyone else — the **medium need for cognition** majority, who could tip either way. To me, this is the most consequential group in the essay. Brooks makes the point that need for cognition is not a fixed trait; willpower is extremely sensitive to context. Which way the middle drifts will decide whether AI produces what he calls extreme cognitive polarization — a world split between minds that atrophy and minds that compound.
As an actual (not just mental) marathoner, I felt personally summoned… Brooks’ warning is sharp. In one study he cites, an AI intentionally gave incorrect answers — and humans accepted them as true 80% of the time. He calls this failure mode cognitive surrender. But what makes his argument especially relevant here is the parallel he draws to endurance. Thriving in the AI age, he argues, will look less like a burst of brilliance and more like sustained intellectual effort — the willingness to keep engaging, questioning, and refining when it would be easier not to. In his framing, the winners are not those who access intelligence fastest, but those who stay in the work longer. The ones who don’t hand over the thinking at kilometer 30.
In other words: when everyone has access to the same intelligence, what differentiates people is no longer how smart they are. It’s how willing they are to keep doing the work.
The productivity paradox, quantified
Now let’s look at the data. The Work AI Index 2026 surveyed 6,000 knowledge workers between December 2025 and January 2026, and the headline numbers are the kind you’d put on a keynote slide: 87% of knowledge workers now use AI. 73% say it makes them more productive. Reported time savings run around 11 to 13 hours per week — nearly a third of a standard workweek.
And then the shock: only 13% strongly agree their organization is performing significantly better because of it. Billions of hours saved — and almost none of it visible at the organizational level. Why?
Part of the answer is a phrase we’ll likely hear a lot more: bot sitting. The report defines it as the hidden human labor required to make AI usable — feeding context, checking outputs, debugging mistakes, re-running prompts, and cleaning up confident-but-wrong answers. Workers spend an average of 6.4 hours per week on it. Roughly half the productivity dividend gets reinvested into supervising the tool that produced it. The report also found that 36% of AI sessions fail outright, forcing a restart or heavy rework.
It gets darker. Fatigued workers eventually lower their standards — the report calls the result bot slop — and around 40% of employees admit to shipping AI-generated work they could not explain or defend if asked. And when AI-generated work fails, heavy users are 3.4x more likely than light users to blame the tool rather than themselves.
Cognitive surrender, measured.
The AI Daily Brief framed this in a way that stuck with me: we keep asking “how can AI help me do the same work faster?” when the better question is “what can I now do that was previously impossible?” Individual time savings do not automatically compound into organizational transformation. That requires redesigning the work itself — which is training, not shopping. Buying a better watch has never made anyone run a faster marathon…
Meanwhile, the front of the pack accelerates
The paradox becomes sharper against the backdrop of what’s happening at the frontier — because even by recent standards, the past week was absurd. What’s driving it is the same shift underneath everything else in this piece: the unit of consumption is no longer a seat. It’s a token. A developer running an agent against a real codebase can consume hundreds or thousands of dollars a month — a number no per-seat pricing model ever contemplated.
Kilometer 30, enterprise edition
Which brings us to my favorite data point of the quarter: Uber blew through its entire 2026 AI budget in four months. Read that not as retreat but as maturation. Budgets, dashboards, governance, exception processes — this is what happens when a technology stops being an experiment and becomes a line item. The sprint phase is over. The conversation inside enterprises has moved from access to allocation, from novelty to ROI.
And here is the uncomfortable part: Uber’s COO admitted it remains genuinely hard to draw a line from all that AI usage to more product actually shipped. The Glean data explains why. Adoption is solved. Transformation is not.
We may be entering a new phase where the first enterprise constraint is not access to AI, but unbounded consumption. Tokens are cheap individually but expensive in aggregate — and without clear task redesign, they scale activity faster than they scale outcomes. Thousands of prompts to refine a slide, hundreds to draft a single email, fleets of loosely coordinated agents producing work that still requires human verification.
The emerging question is not just how many agents can we deploy, but how much work should exist in the first place — and how to harness, orchestrate, and constrain that work so that it compounds into real output rather than noise. In other words: the problem is no longer intelligence scarcity. It is discipline.
The people who keep running
So what actually separates the 13% of organizations where AI gains show up from everyone else? The Work AI Index has a beautiful answer buried in it. High performers don’t bot-sit less — they bot-sit differently. They treat the friction as training: they are more than twice as likely to describe AI as a valuable teacher, and they reinvest saved hours into building new skills rather than simply producing more output. Adoption spreads through example, not mandate — seeing a cross-functional colleague use AI well makes the average employee 5x more likely to adopt, precisely because those workflows have survived contact with real organizational messiness.
That is not a technology story. It is a training story.
Long-distance running taught me that performance is never the product of one heroic effort — it is thousands of unglamorous marginal gains, compounding quietly on days when motivation is nowhere to be found. The models will keep getting better, cheaper, and more agentic whether we show up or not. The frontier labs are running their own race, at a pace none of us can influence. Ours is different.
Nearly everyone now has access to frontier intelligence — which means intelligence is no longer the differentiator. Volition is. Judgment is. The willingness to redesign how you work, verify what the machine gives you, and keep learning after the novelty wears off — that is the race that is actually winnable…
The best marathoners are not the ones who find shortcuts. They’re the ones who keep running!

The biggest news in AI this week comes out of China: Moonshot AI released Kimi K3, a 2.8 trillion-parameter model that is now, by a wide margin, the largest open-weight model ever shipped. It matters because it isn’t just big — it’s genuinely competitive, using a mixture-of-experts design that splits itself into 896 smaller expert subnetworks and activates only a portion for any given task, letting it hit near-frontier performance without frontier-level compute costs. On the numbers that matter: a 1 million token context window, with Kimi’s “Delta Attention” enabling up to 6.3x faster decoding at that scale, and — this is the part that stings — early head-to-head benchmarks have it beating Anthropic’s Fable 5 in 7 of 8 coding arenas, with Fable’s only real edge being speed. Pricing seals the disruption story: K3 lists at $3/$15 per million tokens (input/output) versus Fable 5’s $10/$50 — a fraction of the cost for benchmark parity. Full weights don’t drop until July 27th, so for now it’s API/subscription-only via kimi.com, but the timing — landing right before the World AI Conference in Shanghai, weeks after the US briefly pulled Fable and Mythos over export-control concerns — reads as a deliberate flex: proof that the open-vs-closed gap has narrowed to about one generation, not several.

The AI Daily Brief
“The miracle isn’t that I finished. The miracle is that I had the courage to start.” — John Bingham













"Adoption is solved, transformation is not" is the line I'll be quoting. After ~25 years building software inside banks, here's why I think the gap is so stubborn: the saved hours flow straight into bot-sitting because the underlying work was never governed to begin with. The model doesn't create the mess, it exposes the one that was already there. The 13% didn't buy better AI; they redesigned the work, which inside a regulated institution is a governance problem wearing a productivity costume. The Brooks + Work AI Index pairing lands harder together than either does alone, nicely done, Julia.
