The nuclear interaction: post-modern developments

We take stock of what we have learned in the 25 years since a watershed ECT* workshop, when the now-popular effective field theory methods where first scrutinized by the nuclear-interaction community. Have potentials inspired by Chiral EFT fully replaced more phenomenological approaches? What are their phenomenological limitations? How can they be improved? Have theyodel-independent and systematic description of nuclei with controlled uncertainties? Do we understand the dynamical implications of QCD?
