X launches Custom Timelines powered by Grok, letting users pin niche topics to their home feed with AI-driven personalization, rolling out first to Premium users on iOS

Grok trains on X posts, curates X feeds, which shapes engagement, which becomes training data. That loop homogenizes whatever generates clicks. Crypto anons who called depegs months early don't optimize for clicks - custom timelines surface them last. Paying $8/month to be filter-bubbled by your own engagement history.
