It looks like keynotes from this week's in-person useR! conference will be livestreamed, according to a post on Bluesky https://bsky.app/profile/user-conf.bsky.social/post/3lvlq5egkbk2i
I assume on the YouTube channel https://www.youtube.com/@useRConference_global
Conference schedule: https://user2025.r-project.org/program/in-person/
