Earlier this year, YouTube began rolling out a row of algorithmically recommended videos at the top of the Subscriptions page. The section, labeled "most relevant," surfaces content the algorithm predicts the user will engage with, pulled from channels the user already follows. The subscription feed still exists below it. But the default view, the first thing a user sees when navigating to a page they built through deliberate choices, now leads with what YouTube's algorithm thinks they should watch.

On March 26, Anthropic confirmed the existence of Claude Mythos, an unreleased AI model described internally as "a step change" in capabilities, after a data leak exposed approximately 3,000 unpublished assets in a publicly searchable, unencrypted data store (Fortune, March 26, 2026). The leak was not a sophisticated intrusion. A toggle switch in Anthropic's content management system was left in the wrong position, setting digital assets to public by default (Fortune, March 26, 2026). Among the exposed materials were internal assessments describing Mythos as posing "unprecedented cybersecurity risks" and being "far ahead of any other AI model in cyber capabilities" (World Today News, March 2026).
