I respect your opinion and experience, but FWIW for the readers, I had the completely opposite experience.
The batch did divide into groups. Some people were learning functional programming, others focused on Transformers architecture, while yet others on dynamic programming. But I quickly found a small group of people who were building things that I was interested in, games and AI applications.
In the unstructured time I was able to set my own goals, ship a lot, write a lot, and give a lot of talks on topics that are very interesting to me.
I didn't expect or get any free food from the Recurse Centre -- I was in New York, I had the world's cuisines available to me. I often went on lunch along with other RC members to reasonably affordable places within walking distance.
RC is not a college course with exams and a fixed syllabus -- It was unstructured and self-directed -- and that's what made it so special.
