Confessions: 15 Brutal Truths in Telco sebastianbarros.substack.com Nov. 18, 2025, 4:26 p.m.
Every week, I collect private confessions from telco CXOs. This time, I pulled together fifteen short stories. Small moments that expose the truths our industry keeps quiet. Real voices. Real pressure. Real mistakes. Real opportunities. A clearer picture of telco emerges one confession at a time. A collection of honest reflections from the people who actually run networks and see the industry from the inside every day. 
WiFi and Cellular Are Not Friends sebastianbarros.substack.com Nov. 16, 2025, 7:05 p.m.
The reason these collisions keep appearing is that WiFi and cellular no longer occupy separate roles. They chase the same physics, the same mid-band capacity, the same enterprise environments, and the same edge compute opportunities. The Brussels decision is only the most recent signal that the two stacks are converging on the same territory, and every time that happens, the tension becomes visible.
Telco Layoffs. Inevitable  sebastianbarros.substack.com Nov. 14, 2025, 12:42 p.m.
The layoff wave that started in the technology sector in 2021 reset the rules of corporate finance.More than 500,000 technology workers were cut between 2021 and 2025. In 2023 alone, companies announced 264,220 job reductions. This happened inside firms with operating margins above 25% and cash balances in the tens of billions.Investors rewarded the cuts because they protected earnings and released capital for artificial intelligence programs that require extreme spending on compute, data centers, and model development. Meta declared a Year of Efficiency in 2023, removed 11,000 roles, and the stock jumped more than 19% in a single session. That reaction created a new norm. A layoff became a signal of discipline rather than distress.
Telco Confessions: The AI Bullcrap Audit sebastianbarros.substack.com Nov. 10, 2025, 12:42 p.m.
I’ve spent the last year drinking from the AI firehose, part doctoral research, part field therapy. Between telco boardrooms and academic labs, I keep hearing the same wild claims about.“AI transforming everything.”To separate physics from PowerPoint, I asked two of my research partners to join me for an experiment: let’s run the industry’s favorite AI myths through a Bullcrap Meter.
Neuralink Rival Synchron Raises $200 Million for Brain Implant www.bloomberg.com Nov. 6, 2025, 2:47 p.m.
Several companies are building brain implants to allow people to communicate with computers directly through their minds, benefitting those who are paralyzed, blind or otherwise have limited use of their limbs or sensory organs. In the long term, some entrepreneurs and investors think that brain implants will become everyday consumer technology, like cellphones. No such devices are approved by government regulators for long-term medical or recreational use.
La bataille sino-européenne autour des semi-conducteurs ! fr.linkedin.com Nov. 5, 2025, 9:19 p.m.
Dans cette bataille, les trois géants européens se retrouvent tiraillés entre la volonté politique de l’UE et la réalité économique de leur premier marché. Visiblement, ils n’ont pas d’autre choix que d’accepter les quatre conditions imposées par Nexperia Chine.
Cette mystérieuse start-up américaine qui recrute des consultants pour les remplacer… grâce à l'IA www.lesechos.fr Nov. 5, 2025, 8:25 p.m.
Mercor aurait recruté près de 150 consultants afin de bâtir une intelligence artificielle capable de les assister au quotidien, selon Bloomberg. Le secteur s'interroge de plus en plus sur l'arrivée en force de cette nouvelle technologie.
Promesses et business plan : jusqu’où peut-on jouer avec les hypothèses ? solutions.lesechos.fr Nov. 5, 2025, 8:20 p.m.
Les startups misent sur une croissance rapide plutôt que sur une rentabilité immédiate. Mais entre ambitions démesurées et réalité du terrain, l’art du business plan consiste à bâtir des hypothèses solides sans céder aux mirages des tableurs. Un plan crédible doit articuler une vision, des données dûment étayées et une capacité d’adaptation face aux aléas. La crédibilité d’une équipe tient moins à la précision de ses prévisions qu’à sa lucidité et à sa faculté à s’adapter pour garder le cap lorsque les promesses se confrontent au réel.
How to Get Our Telco Mojo Back (We’re Doing It All Wrong) sebastianbarros.substack.com Oct. 29, 2025, 11:37 a.m.
Telco used to be the most exciting place on Earth. We were the people who made the impossible happen. We connected continents, carried the first digital signals, and built mobile networks that turned communication into a human right. We were the engineers who bent physics to our will. Then something happened. We turned into administrators of connectivity. The industry that invented the digital age now spends more time in regulatory filings than in labs.
WoW: Nvidia Buys Into Nokia  sebastianbarros.substack.com Oct. 28, 2025, 5:09 p.m.
When Nvidia takes a billion-dollar stake in an old-guard telecom vendor, it’s not a financial gesture but a signal. A signal that the AI arms race is moving from datacenters into the network fabric itself. On October 28, 2025, Nokia announced that Nvidia will invest $1 billion in newly issued shares, acquiring roughly 166 million shares, or about 3.5% of the company, and forming a deep strategic alliance to co-develop 6G and AI-native networking technologies. Nokia’s stock jumped 18 % within hours.
Everyone Talks About AI. Few Understand What It Means for Telcos. sebastianbarros.substack.com Oct. 23, 2025, 4:05 p.m.
Most telcos still haven’t come to terms with what AI truly means for their future. This is a 2007 iPhone moment on steroids, not another radio upgrade, not a “TechCo” rebrand, and certainly not a digital transformation checklist. AI is changing the very physics of how humans, and now machines, connect and interact across the digital and physical world.
The Telco identity crisis sebastianbarros.substack.com Oct. 20, 2025, 3:12 p.m.
Before 2007, Telcos knew precisely who they were.They built networks. They connected nations. They carried the weight of communication with pride. Telcos were infrastructure institutions: disciplined, engineered, predictable. Then, in 2007, everything changed. The iPhone turned connectivity into an afterthought. The network disappeared behind the screen, and the center of gravity shifted from infrastructure to experience. For the first time, the telco wasn’t the main act; it was the invisible stagehand behind the digital revolution.
Confessions of a Telco Executive: What Vendors Know (and We Deny) sebastianbarros.substack.com Oct. 13, 2025, 12:56 p.m.
This week, the confession comes from the other side of the table. From the people who have built our systems, sat through our meetings, and quietly watched the same story repeat across continents: the vendors.They have seen how decisions are made, how timelines are invented, and how politics replaces logic. They know when a project will fail before the first contract is signed. They understand that most telcos no longer innovate; they negotiate. Procurement has replaced product. Compliance has replaced creativity.
Terres rares : tout comprendre aux annonces de la Chine qui font trembler les importateurs européens www.latribune.fr Oct. 10, 2025, 1:13 p.m.
Les annonces de Pékin sont lourdes de conséquence pour les chaînes d’approvisionnement déjà fragilisées : désormais, n’importe quel produit, composant, ou technologie incorporant des terres rares ou savoir-faire chinois, devra obtenir une licence de Pékin pour être exporté, y compris si le produit se trouve déjà hors de Chine et si l’expédition se fait entre deux pays tiers.
The Evolution of the Telco CEO: 2000–2025 sebastianbarros.substack.com Oct. 8, 2025, 3:30 p.m.
Telco CEOs have changed as much as the networks they run. Two decades ago, most were engineers obsessed with coverage maps; today, they’re diplomats managing politics, investors, and cloud partners.
Confessions of a Telco Executive: The Telco Fallen Empire sebastianbarros.substack.com Oct. 6, 2025, 12:19 p.m.
In 2008, Europe’s telcos were the most valuable companies in technology. Today, their worth has fallen by more than 80%. We spoke to insiders to understand how the empire collapsed.
The Lie of AI Agents: What They Really Can (and Can’t) Do sebastianbarros.substack.com Oct. 1, 2025, 11:40 a.m.
In classical AI, an agent is nothing mystical. It is a system that perceives, makes decisions, and acts within an environment. A thermostat is an agent. A Roomba is an agent. The term never implied consciousness or autonomy. It was a clean abstraction for building systems that respond to inputs and produce outputs in pursuit of a goal.In the era of generative AI, the word “agent” has been hijacked. Vendors present agents as if they were digital employees who can sit in your enterprise, learn the ropes, and work unsupervised.
L’Albanie nomme un ministre généré par IA pour lutter contre la corruption creapills.com Sept. 22, 2025, 10:25 a.m.
C’est une première mondiale qui fait déjà couler beaucoup d’encre. En Albanie, le Premier ministre Edi Rama vient d’intégrer à son gouvernement un ministre… totalement virtuel. Baptisée Diella, cette intelligence artificielle devient officiellement ministre en charge des marchés publics. Une décision symbolique et politique qui entend marquer un tournant radical dans la lutte contre la corruption.Son rôle ? Superviser l’ensemble des appels d’offres publics du pays, secteur historiquement sensible en matière de corruption. Selon le Premier ministre, l’objectif est clair : rendre chaque denier public parfaitement traçable et transparent. Grâce à l’IA, plus d’arrangements opaques ni de conflits d’intérêts. Juste des algorithmes et des critères objectifs.
Meta veut enterrer le smartphone www.servicesmobiles.fr Sept. 19, 2025, 8:47 a.m.

The Telco Big Bang: AI Will Change Every Atom of Telecom Networks sebastianbarros.substack.com Sept. 19, 2025, 5:58 a.m.
Telecom networks run on models. Erlang distributions, busy-hour factors, peak-to-average ratios, and oversubscription levels are the tools that let operators design networks without provisioning for absolute maximum demand. The assumption is that human behavior follows statistically smooth curves, allowing for the forecast of aggregate demand and the absorption of rare spikes with a margin of overcapacity.AI breaks this foundation. Agent-driven traffic is non-ergodic: past averages do not predict future bursts. Each inference request is unique, decorrelated from the next, and capable of spawning chains of sub-requests across geographies.
