A Celebration of Blogging, Truthseeking, and Original Seeing
Fri, May 30th — Sun, June 1st | Lighthaven, Berkeley CA
LessOnline is a festival celebrating truthseeking and blogging. It's an opportunity to meet people you've only ever known by their LessWrong username or Substack handle.
The goal is to bring together a "mostly-online subculture of people trying to work together to figure out how to distinguish truth from falsehood using insights from probability theory, cognitive science, and AI."
The weekend will be filled with talks, workshops, dance parties, and late-night conversations around the fireside.
This is the second year of LessOnline. Last year over 400 people attended, and we're expecting more this year.
The sites below embody the virtues we are celebrating. Each author below has been offered a free ticket to LessOnline.
"She was strangely unaware that she could look and see freshly for herself, as she wrote, without primary regard for what had been said before."
...a trip to an alternate universe, a road not taken, a vision of a different life where you get up and start the day in dialogue with Agnes Callard and Aristotle and in a strange combination of relaxed and frantically go from conversation to conversation on various topics, every hour passing doors of missed opportunity, gone forever.
I'm probably giving you the idea that the Bay Area tech people are a bunch of weirdos. Nothing could be further from the truth. In general, I found them to be smarter, more rational, and even nicer than the average human being. If everyone in the world were like these people, even communism might have worked.
I got to have many long (and short!), inspiring, and occasionally intimate discussions with people I really admired… you feel like you're at home the whole time you're there… if you weren't there, you missed out, but there's always next year.
