Mechanistic Interpretability Still Holds Value

This reply discusses whether mechanistic interpretability (mech interp) can provide insights beyond pure behavioral analysis.
The author believes mech interp already offers additional information, which is also visible in Claude's model card. However, they feel the future outlook is being viewed too pessimistically:
- There is no need to be overly pessimistic about the prospects of mech interp;
- There is no need to be overly pessimistic about alignment timelines;
- But these two are fundamentally different issues.
