Mechanistic Interpretability Research Will See Exponential Growth in the Next Three Years

The author argues that AI 2040's prediction of mechanistic interpretability (MI) only maturing by 2035 is too conservative. They note that MI—a field that didn't even exist 9 years ago—has already produced critical breakthroughs like SAEs, natural language autoencoders, and J-Space over the past three years.

Driven by natural field growth and the boost from AI-assisted research, the author estimates that the volume of MI research completed in the next 3 years will be 2 to 40 times the sum of all previous years combined.
