* Three distinct types of AI - generative, predictive, and content moderation

* Generative AI

- Image generatoors typically use diffusion models, which transform random noise into coherent visuals by learning from exxtensive datasets.

- One key issue: unregulated use of artists' work

* Three distinct types of AI - generative, predictive, and content moderation

* Generative AI

- Image generators typically use diffusion models, which transform random noise into coherent visuals by learning from extensive datasets.

- One key issue: unregulated use of artists' work

- Chatbots actually generate text by predicting word sequences, not by understanding context

* Predictive AI

- AI models often fail to account for how their own choices change the circumstances they predict.

- Because these models rely on what’s worked historically, they often miss what actually needs to be measured.

- Automation bias: over-reliance on AI

- Inaccurate predictions can very seriously affect individuals from underrepresented populations

* Content Moderation AI

- One major limitation is AI’s inability to appreciate context and nuance

- Another issue is cultural competence

- Social media platforms use two main AI techniques: fingerprint matching to detect copies of banned content; machine learning to identify patterns in new content

- Collateral censorship: platforms often over-moderate, removing more content than necessary to avoid legal/compliance risks
