My talk (Taylor et al. 2023) from this year’s SVPCA is up! The talks were not recorded live. But while it was fresh in my mind, I did a screencast of my own, and posted it on YouTube (CC By). For the conference, I spoke very quickly and omitted some details to squeeze it into a 15-minute slot. In this version, I go a bit slower and make some effort to ensure it’s intelligible to an intelligent layman. That’s why it runs 21 minutes.
