Toby Walsh explains why AI can answer confidently despite uncertainty, including the continuing problem of fabricated sources and links.
The brief
People routinely underestimate how long projects and everyday tasks will take, a small forecasting error that opens into a larger question about how minds model the future.
Cassandra Vieten reframes imagination as a core cognitive tool for memory, planning, perception, problem-solving, and bodily experience—not merely a talent for artistic invention.
Vieten also describes wide variation in imaginative experience, including vivid visualization and aphantasia, while arguing that imagination can be developed through deliberate practice.
Toby Walsh contrasts human intelligence with AI that can draw on vast written material yet produce confident errors, fabricated sources, and privacy risks when conversation history is involved.
The episode closes with the zipper merge: using both lanes until the merge point and taking turns can keep more roadway in use and reduce congestion.
