Kamala Harris used yellow and pink flowers to illustrate how social media algorithms can repeatedly show people similar content based on their previous activity. Speaking about AI, TikTok and Instagram, she warned that this personalisation may narrow what users see and could influence how Americans consume information before elections.

Harris said users should recognise when they are being targeted and find ways to resist algorithmic manipulation. Her comments prompted mockery from Fox News presenters, while also reviving criticism of her previous explanations of AI; she has separately urged international agreements to limit dangerous AI uses and establish testing standards.
