At 12 pm EST today (Jan 26th), Marcus Hutter will be answering questions on his latest book (An Introduction to Universal Artificial Intelligence): https://uaiasi.com/2026/01/24/qa-with-marcus-hutter-at-the-final-meeting-of-the-iuai-reading-group/
Formally, this is the final meeting for the reading group, but feel free to drop in if you have read (most of) the book independently.
