Opposing ideas can be symbiotic because each side sustains attention on the other—ongoing debate prevents consensus and keeps both ideas circulating longer.
Generative models are often trained first to mimic data distributions because unsupervised learning captures general patterns, and then fine‑tuned with supervised or reinforcement methods to specialize on tasks like summarization or editing.
