In my response to the commentaries from a collection of esteemed researchers, I reassess and eventually find largely intact my claim that human tool use evidences higher social and non-social cognitive ability.

For that, one needs to incorporate them into population-dynamic models of cultural evolution. I briefly describe my current and future work on this.
