Why Transformers Struggle with State Tracking and How Recurrence Could Fix It

The DeepMind paper “The Topological Trouble With Transformers” reveals that the Transformer architecture inherently fails at state tracking, making chain‑of‑thought prompting only a costly patch, and proposes returning to recurrent mechanisms—such as looped or sequence‑wise recurrence—to achieve true, continuous memory.
