Yes, I figured that is what you meant, which is why I then explained why it still sucks. What if I don't want to eat something entirely then and there in the konbini I bought it...? What if I have trash from some other source?

> it seems to have been mostly a response to citizens avoiding rubbish collection fees at home by taking household waste to public bins.

Yes, that was highlighted in the LLM report. And is an example of the perverse dynamics and poverty mindset, where an entire society is distorted in the name of conservation, where the high usage of trash cans becomes a reason to not have them. (I am still thinking about the multiple 3/4-star luxury hotels I stayed in which provided some of the lowest-quality gas-station-tier toilet paper I have ever used - a false economy all the more unjustifiable given how little toilet paper a guest would use thanks to the wonderful bidets!)

> but we were prepared

Precisely. I was confused for the first week: "how does this work? How are the locals throwing their trash away away? Surely they don't just reorganize their lives around this limitation, and tolerate things that few other societies tolerate, and let an obsession with litter and recycling run their lives and dictate when and where they can eat or even just drink some water on a hot humid day? There must be some trick or convention I am not getting, maybe some trash cans hidden away somewhere under an unfamiliar appearance." And then I realized, "oh. They do. That's how it works." And I too reorganized my life to submit to the trash planners.

The absence is well-known and described in places like Wikipedia. Also, how many major capital cities in Japan should I spend time in before it's not 'anecdata'? Should I get a sample of another 10 or 20 Tokyos before you're satisfied?

FWIW, I did a LLM research report about numbers, and they pulled up some interesting cites: https://gwern.net/doc/japan/2026-11-03-gpt6astra-japansmissi... Places like Osaka have deliberately removed their city trashcans (from 5000 to zero since 2007, while Kyoto apparently got rid of 500 recently), and the vending machine trashcans are inadequate because they're only supposed to be for bottles but of course pick up a lot of other trash because what other option is there, while konbinis report problems with people using their tiny little trashcans a lot. There's also some interesting dynamics here where the overuse of trashcans becomes the justification for removing them, thereby externalizing all the costs onto people (especially tourists, according to the Japan Tourism Agency's regular large-scale surveys, where a shockingly large percentage single out trash cans as a problem in their visit).

> but there are plenty that are adjacent to where you are likely generating rubbish (or recycling) - eg. konbibis.

As already noted, I didn't see many adjacent to konbinis. (Inside them, sure, but that is definitionally not a 'public rubbish bin'. That's a private one, and we felt awkward just going into stores to use their trash. Similar to using a store's restroom without any intent of shopping there. Some "plenty"!)

> I suspect spending all your time in the frustratingly tourist-dense triad likely skews your experiences of the country

Yes, I expect it skews my trash bin prevalence too high. Because tourist-heavy places should have more, not less.

As for crediting by name: the formatting is as in the original, and I am not responsible for that; I am responsible for the URL and PDF metadata, both of which credit Greg Egan (as I put a lot of work in setting correct PDF metadata in general to be a good citizen).

The only important prediction Kelly made was a complete rejection of the Singularity. It is also probably the prediction that sentiment has changed on the most in the direction away from Kelly, since 2016. After a decade of evidence and updating, far more people believe in that view of our AI future now than they did then.

(His 2017 https://www.wired.com/2017/04/the-myth-of-a-superhuman-ai/ hasn't aged well either.)

If you have ideas, you could try vibecoding them and see if they work. The page should be fully self-contained and have everything an agentic LLM could need.

FWIW, I do not force anyone to, because the URL I shared on my Twitter/Substack/Reddit has the '#play' hash-anchor to skip to the prototype game, and leave Claude's writeup for those who care. Take it up with OP if you dislike where they pointed the submission to. I provided the necessary standardized metadata for readers to skip to the part they want (clearly hyperlinked at top), the rest is up to them.

> You do see how that's all garbage, right?

I don't, because that's not true. There's a lot of interesting stuff in just the parts you quote as 'garbage'. For example, I was surprised by the exact solver and constraint optimization that Claude chose to do, which led to some of the more interesting features of the puzzle like the hinting feature or the 'par' challenge (and the existence of multiple solutions but some of which are optimal, and challenging you to reach optimal rakes, is one of the things that distinguishes it most from similar puzzles like 'Cardinal Chains' or ZPG). And this is one reason the title is 'Designing a Zen Garden Raking Puzzle', as opposed to just 'A Zen Garden Raking Puzzle', because Claude/Astra took it in some interesting directions compared to my original proposal, due to their coding and algorithmic prowess. Had it just been me, I probably would've gone for a unique-solution approach like everyone else.

> The game widget itself takes up 3 pages on mobile, because of all the Claude web design.

Not sure what you mean. I just opened it up on my Pixel phone and it looks entirely playable on one screen to me. Are you referring to the level table of contents at the bottom or the poems...? Obviously there's no problem with those taking up more than 1 page because you don't need to consult them to play. (Anyway, I'll note for the record I've been tweaking it since the first uploaded version to streamline the UI/UX a bit based on Said Achmiz's feedback, so the latest version may be more to your taste.)

> This makes me kind of sad for the Gwern we've lost.

I'll fetch the smelling salts, but I'm surprised at this reaction to a prototype game implementing an idea I had.

ZPG winds up not being as interesting, I think, because it doesn't figure out how to take the core idea of raking and twist it into more interesting puzzles, which is the classic puzzle approach: find a clean core mechanic, and then escalate on it.

That aside, did you enjoy the game?
