Has there been a business started based on work done there? Publishable research results? (that second one is actually a pretty low bar, and yet if there is something it is not easily discoverable)
I don't get it. Why would you ask if an adult daycare leads to a business or new discoveries? Daycares are for nurturing curiosity and fostering development in a socially engaging environment—much like the Recurse Center—not for publishing papers.
You are missing the point. On the line between explore and exploit, RC is basically 100% explore. The point is to learn, and more importantly, to flex the muscle of learning without being taught. And to participate in a community of kind and curious people who are also motivated to do the same.
From what I see, this is more of a sabbatical time to just explore and enjoy programming without needing a productive end. I've been considering it myself.
It's weird to say that about a YCombinator-affiliated event on a YCombinator forum. I'm not especially fond of YC but there's pretty clearly potential to make valuable connections in this sphere.
Here is an honest good faith answer to a pretty aggressively hostile question:
Adult daycare is almost the opposite of what Recurse center is. Recurse is largely unstructured: people do what inspires them and make their own plans. You will find more structure, hand holding and mandatory time wastes in virtually any business than you will at Recurse Center.
A 12 week batch is not a lot of time to carry out a major research project, but it is generally not intended to treat this as a start up incubator. There are other places for that kind of activity. Recurse is a place to freely learn and explore. There are a few companies that have emerged but they are not huge money machines (most companies are not). There is also some interesting research that is done.
Some things that pop into my head immediately are:
Dan Luu's studies of Motion to Photon Latency in keyboard input [1]
Raph Levien's work on Xi [2], and Andrew Kelly's work on Zig [3].
I'm sure there are other people could dig up more examples, but that really isn't the point. A school's purpose is to produce educated people. Recurse is more of an unschool but the aim is to help people learn and think - it should be judged on those terms first and foremost.
Even if for the sake of argument its conceded it's a "daycare", what's wrong with that? No one's being forced to go there. It's free for the participants. There's no harm in a group that facilitates people exploring what interests them in a setting where others are doing the same.
The main problem I see with RC which has prevented me from applying is there’s no stipend or housing. Most people can’t afford a summer in NYC without pay. So I’m not sure who the target audience really is, I guess wealthy SV engineers.
Not really something you can control, but RC always feels "unauthentic" whenever people write about it.
It is often portrayed like an old-school hackerspace or makerspace but it's definitely not. It has an explicit corporate background, and it always feels like that is somehow hidden.
In these comments there is a comment that claims that RC is not for business builders and networking, then immediately gets disproven by a quote from its very website. This shows that you have an actual image/brand problem.
It is similar to how the term "hackathon" evolved. In the old times it was people coming together who worked on shared goals (like a FLOSS project) but only communicated via mailing lists and probably would never met in person otherwise. A hackathon was often an emotional thing, involving poor people travelling to the other side of the planet to meet their online friends to drink beer and finally have a whiteboard to communicate some complex ideas. Then corporations came and organized soulless "hackathons" and turned it into an idea farm and talent recruitment. The term "hackathon" is pretty much burnt completely nowadays.
So anything that feels like it gets subtly used by corporatism just naturally gives techies the ick. It is not the first time this bait-and-switch happens, so people are fair to assume intent.
I say you cannot control it, as obviously the public image comes from those blog posts of RC "Alumni" (Another great example: that term alone gives me the creeps). And those people have the right to feel excited about a nice experience that it probably was for them.
But Recurse Center should probably be proud of the corporate background and actively counteract the impression of being a hobbyist makerspace that just has better inventory and manpower.
> This included what was probably the most interesting part, writing the tricky recursive code to implement the match statement.
Back in school I found this book[0], "The Implementation of Functional Programming Languages". Flipping through it was very neat because it kinda demystified the nuts and bolts of implementing the "fancier" functional programming features for me.
Chapter 5 is about implementing pattern matching.
You read this kind of stuff and realize how easy things become when you just tackle a problem with the right mindset and abstractions. And this is a book from 1987! We've always had decent answers for a lot of the stuff.
I think it's interesting to flip through if you're a language implementer, though helps to be comfortable with reading some stuff sideways and not understanding every detail.
It is even worse, we had decent answers for some of the stuff back in the 40s, 50s and 60s (e.g. Dijkstra's work on concurrency, before there even were computers to run them on.)
Someone will reply to my comment with Lovelace or Babbage or Pascal :-/
Reading this conjured some feelings in me. At various points in my career, I’ve wanted to take a sabbatical and go to RC. Having spent the last year in the agentic coding world, the idea of writing code by hand seems quaint and outdated. Many have spoken of this feeling of loss so I’m not saying anything new here, but for some reason reading about RC in 2026 specifically cemented the idea that I’ll probably never write anything by hand again.
> The goal of the game is to give hints to a secret word without giving the same hint as another player; it was shocking how often all the agents playing would give the same hint, even at temperature 1. We resolved this by giving them all “personalities” which were really just topics; for example we’d be telling one agent to think about things in the context of sports, so their clue for “shell” might be “defense” or something, whereas the agent told to be a hippie might say “cancer” for the zodiac’s crab.
Mode-collapse is characteristic of pretty much all chatbots post-davinci-002 and a major challenge to anything creative or game-like.

It doesn't really attract the YC kind of people either.

Greg Brockman went through Recurse in Summer of 2015, and co-founded OpenAI in December of 2015.
