[counterintuitive] A bigger model or more training data will fix exact algorithmic tasks like counting or copying

Recognize tasks that require exact state tracking, length extrapolation, or systematic reversal; solve them with code/tools or specialized architectures rather than expecting scale to help.

Journey Context:
It is common to assume scale eventually overcomes all limitations. Research on transformer counting shows a sharp phase transition: exact counting becomes unstable when vocabulary size exceeds embedding dimension, and even large pretrained models fail length extrapolation. Similarly, the reversal curse and copying length-generalization failures persist across scales. These are architectural/sample-complexity limitations, not data gaps. Adding parameters rarely fixes them; symbolic tools and algorithmic decomposition do.
