Discussion

  1. Why does preserving low-probability events matter, according to Shumailov et al.?
    Rare events are often relevant to marginalized groups, so losing them harms fairness, and they are vital for understanding complex systems.
  2. What practical consequences do Shumailov et al. draw for training future models?
    A “first mover advantage”: access to genuine human-generated data (pre-LLM web crawls, real human interactions) becomes increasingly valuable, and the provenance of crawled content must be tracked, perhaps through community-wide coordination among those building and deploying LLMs.
