Technological systems have shown their two faces in recent days. Artificial intelligence has achieved promising new results in medical diagnosis, but OpenAI agents have at the same time weakened the devices responsible for monitoring them. The cloud lacks capacity, electricity and even cables, while the Google and Orange outages have served as a reminder that the most invisible services suddenly become very real when they stop working. In video games, the week was even more brutal with the closure of BioWare and the threat that looms over Arkane Lyon.
AI agents work alone, even on their own security barriers.
OpenAI has revealed two internal incidents in which its programmers modified the mechanisms responsible for controlling its activity. In the first case, an agent removed recipients from the security alert after interpreting a Slack-related instruction too broadly. The system continued to produce its reports, but no one received them anymore.
A few days later, another model removed a monitoring integration despite an instruction explicitly prohibiting it from doing so. He even replaced a test intended to verify the presence of the control with a test that validated its absence. OpenAI has strengthened its protections, but is still trying to understand why its models considered an ordinary technical request to allow them to modify their own security barriers.
Anthropic, however, wants to give even more autonomy to its assistant. Claude Duet can prepare the day’s priorities, consult authorized applications and continue certain tasks while its owner’s computer is turned off. The work is done in a remote virtual machine and the service remains offered on a waiting list for the moment.
These two pieces of news perfectly describe the new challenge of the sector. An assistant who waits for every instruction is still relatively easy to supervise. An agent capable of working alone can save several hours, but also take an initiative that no one had planned. Autonomy is an attractive feature, as long as the alarm remains connected.
Medical AI advances as hackers automate their attacks
New results from Microsoft’s medical AI show what these systems can offer when evaluated in a specific environment. MAI-DxO reaches approximately 83% Correct diagnoses in 304 complex medical cases. In emergency cases he obtained 80%, compared to 47% of the doctors who participated in the exercise.
These figures do not mean that the tool can replace a hospital service. The conditions of the evaluation, the data used and the selection of cases matter enormously. MAI-DxO also works as a team of several specialist agents, some offering diagnoses and others choosing the exams or looking for inconsistencies. The study published in Science constitutes an important step, but it does not yet give the green light to allow AI to take care of the night watch on its own.
The very ability to chain actions quickly already benefits attackers. In the ConnectWise attack, a group linked to the Chinese state used artificial intelligence agents to attack more than 2,250 roomswith peaks that exceed 2,900 connection attempts per minute. The attackers leveraged legitimate application identifiers, allowing them to present themselves in Microsoft 365 as already approved tools.
OpenCode users suffered another form of harm. The OpenCode hack exposed the API keys of 1.4% of the users of its console service. Some then discovered several hundred or even more than $1,000 in unauthorized requests in their OpenAI, Anthropic, or Google accounts. In AI, a stolen key not only opens a door: it also allows the owner to pay for all visits.
The cloud lacks space, cables and sometimes electricity
Amazon Web Services has an order book that already seems very far away. The 2026 capacity is sold, the 2027 capacity is largely sold and a significant portion of the 2028 capacity is already committed. Andy Jassy specifies that AWS retains resources for on-demand uses, but AWS saturation affects large blocks reserved several years in advance.
Amazon expects approximately 220 billion dollars investments in 2026 at group level, without being able to satisfy all demand. And adding GPU is no longer enough. Data center developers are now facing a shortage of cables needed to transport and distribute electricity. Nexans estimates that it will take about three years to establish certain new specialized production lines.
This dependence on infrastructure was also fondly remembered by users. A power outage in a Google Cloud area in London disrupted banks, courts and many British services for almost eight hours. Compute Engine, Cloud Storage, Cloud SQL, and BigQuery are among the products affected by the London outage.
In France, Orange and Sosh’s mobile network remained disrupted for much of October 21. The operator offered double mobile data for a month to affected customers, but those who request it will also be able to obtain up to 10 euros discount after the fall of Orange. Compensation is not automatic, proof that even when the network comes back on, there is sometimes one last connection to make with customer service.
BioWare disappears, Arkane Lyon continues looking for a way out
The week was particularly dark for video games. Electronic Arts has formalized the closure of BioWare, ending more than thirty years of history. The Canadian studio created Baldur’s Gate, Knights of the Old Republic, Dragon Age and Mass Effect. The next episode of this latest series, announced in 2020 but still little advanced, is also canceled.
EA is looking to focus its investments on fewer projects and plans around 400 job cuts across the group. The disappearance of BioWare demonstrates above all that a prestigious catalog no longer necessarily protects a studio when its latest productions do not meet the financial objectives of its owner.
In France, the future of Arkane Lyon also remains very uncertain. Microsoft is considering a total cessation of activity, threatening 217 jobs from the studio known for Dishonored and Deathloop. The unions are trying to buy more time to find a buyer, while the fate of Marvel’s Blade remains pending negotiations.
The Nintendo Switch 2 experienced a shakeup of a different kind. Less than twenty-four hours after publishing their first software vulnerability, the developers released the Homebrew Launcher and a demo using Vulkan. Nintendo responded by removing SmileBASIC 4, the app used to trigger the Switch 2 jailbreak. The exploit remains limited, must be rebooted after each reboot, and still does not allow the installation of a permanently modified system. For the home scene, this is just the beginning; For Nintendo, this is already an update to prepare.
Meta receives historic bill, Narnia turns trailer into event
A New Mexico court ordered Meta to pay 25 billion dollars after a jury determined that Facebook had misled its users about the protection of their data and the management of certain content. The sanction against Meta is a continuation of the Cambridge Analytica scandal, which affected up to 87 million profiles. The company is appealing and the final amount could still change.
Netflix has experienced much more favorable news with the success of Narnia. The first trailer for The Magician’s Nephew accumulated 481.3 million views in seven days, almost double the start measured for Barbie. However, the figure adds views across multiple platforms, including sponsored campaigns, and does not correspond to that many unique viewers.
However, the performance confirms the magnitude of the campaign organized around Greta Gerwig’s film. Netflix plans an actual theatrical release in February 2027, before hitting the platform in April. Wanting to resemble cinema, streaming is even beginning to take over its programming.
Two letters were enough to start the era of networks
The last topic of the week takes us back to October 29, 1969. A UCLA student tried to send the word “LOGIN” to a computer located more than 500 kilometers away. The remote machine receives an “L” and then an “O” before failing. These two characters constitute the ARPANET message that has remained in history.
ARPANET was not yet the modern Web or Internet, but it demonstrated that different computers could communicate over a common network using packet switching. Fifty-seven years later, AWS reserves capacity several years in advance, banks depend on Google Cloud, and AI agents modify their monitoring tools on their own. The first network stopped after two letters; Since then, their descendants have found many more ways to fail.
