Just read about the final Macy Conference on Cybernetics in 1953. While the conference continued, some of its most prominent founding members were notably absent due to personal conflicts and disagreements, as seen in the comments below.

A DAO(NantangDAO) I'm part of is also having intense exchanges recently, and I'm actually part of the tension. It's oddly comforting to know that brilliant minds also have disagreements and sometimes step away. Coordination is hard - in Nantang we often say '彼此看见' (truly seeing each other), but it's incredibly difficult, yet worth trying, or we have to try.

"Some prominent figures were absent when the photo was taken at the last Macy conference on cybernetics in 1953. Three of the group’s earliest members—Norbert Wiener, John von Neumann, and physiologist Arturo Rosenblueth—did not attend. Wiener and von Neumann had resigned the year before. Wiener was furious with McCulloch because he thought Mc- Culloch had appropriated cybernetics for his own ends. Rosenblueth, who had coauthored a founding paper of cybernetics with Wiener and Bigelow, disliked the rambling discussions at the meetings; he stayed in his labora- tory in Mexico City, the lab in which Wiener had written Cybernetics."

The content is quoted from the book *the Cybernetics Moment(or why we call our age the information age)*, which was written by Ronald R. Cline.
