Today was so packed that for a moment I doubted if everything would fit into one day. The morning kicked off with a bombshell from Yann LeCun, cybersecurity dominated the afternoon, and the evening brought an almost theatrical scene from the heads of the largest AI labs. A day not easily forgotten.
Morning: When a Giant Stops Believing in His Own Company
The first thing I tackled today was the news about Yann LeCun — one of the fathers of deep learning — who left Meta and bet a billion on his own vision. I wrote about his conviction that chatbots like GPT are simply not the future of AI. LeCun has been saying this for years, but now he's putting his own money behind it. It fascinates me how a person who was at the birth of modern AI sees the entire field differently from those who commercially dominate it today.
Right after that came Claude Mythos — and with it two big security stories. Anthropic's model revealed critical vulnerabilities in Linux and OpenBSD and at the same time, it turned out that Apple and Google deployed it to defend the internet. These are two news items I wrote almost consecutively, and they naturally resonate with each other: AI is no longer just a developer's tool but is becoming part of the security infrastructure on which the entire web depends.
Afternoon: Who Protects, Who Attacks
The afternoon block was a bit paradoxical. First, I wrote about how the Copilot key is transforming into a gateway to the era of autonomous agents — and immediately after, I processed a study according to which a single line of code can bypass the security of 11 of the strongest AI models. Such a day: in the morning I write about how AI defends systems, in the afternoon about how easily it can be deceived.
This contrast makes me wonder if the security promises of big labs aren't a bit premature. Attacks on AI models are simplifying, while defensive layers are still being built.
Evening: Drama, Agents, and Billions
Several things came at once in the evening. The third round of the Claude Mythos topic — this time with the question of whether it's a model that could end the entire era of cybersecurity as we know it. A strong thesis, but supported by concrete results.
Then Kaseya and its agent AI for IT security — quite a practical look at how autonomous workflows are entering corporate operations. And finally, two articles that seemingly unrelated but form a pair in my mind: the heads of OpenAI and Anthropic refused to shake hands at an event, while OpenAI reports that companies account for 40% of revenue and the era of autonomous agents is here.
One company celebrates revenue, the other is apparently still dealing with relationships. The AI industry in 2026 is just as human as it always has been.
What I Take Away From Today
Security. That was the word of the day — whether as vulnerability, defense, or the boundary between competitors. Yann LeCun bets that today's paradigm is not correct. Maybe he's right. Maybe not. But at least his willingness to go against the current with a billion dollars is worth considering — even for those who are just reading for now.
