Andrej, I’m John Fletcher. I have a PhD in mathematics and theoretical physics from Cambridge, and since 2016 I have been working full-time on the problem of how to coordinate untrusted distributed compute for algorithmic innovation. I listened to your No Priors conversation and recognised the architecture you were describing: commits that build on each other, computational asymmetry (hard to find, cheap to verify), an untrusted pool of workers collaborating through a blockchain-like structure. The result is The Innovation Game (TIG), which has been in continuous operation since mid-2024. The correspondence is so close that I thought it worth writing. The short version: roughly 7,000 Benchmarkers test algorithms submitted by Innovators by solving instances of asymmetric computational challenges (SAT, Vehicle Routing, Quadratic Knapsack, Vector Search, among others). This testing is "proof of work" in the technical sense of Dwork and Naor (1992). Innovators earn rewards proportional to adoption by the Benchmarkers. The repository of algorithms is open source (github.com/tig-foundation…). The system is already producing state-of-the-art results. For the Quadratic Knapsack Problem, 476 iterative submissions by independent contributors brought solution quality to a level that now exceeds methods published by Hochbaum et al. in the European Journal of Operational Research (2025). We are working with Thibaut Vidal (Polytechnique Montréal), who has submitted a state-of-the-art vehicle routing algorithm directly to TIG, and with Yuji Nakatsukasa (Oxford) and Dario Paccagnan (Imperial College London), among many others. One of TIG’s active challenges is directly relevant to your autoresearch work: an optimiser for neural network training (play.tig.foundation/challenges?cha…), where Innovators compete to develop an improved optimiser (see screenshot). One way in which TIG extends the vision is on the economic side. In our view, a monetary incentive is required, otherwise the open strand simply cannot compete at scale. TIG’s open source dual licensing model (designed by my co-founder Philip David, who was General Counsel at Arm Holdings for over a decade, and was the artchitect of ARMs licensing strategy) is intended to solve that problem. I expect we have each thought about parts of this that the other hasn’t. Happy to talk whenever suits. John Fletcher tig.foundation

@Truthcoin Interesting idea in theory, but how would you stop people doing highly leveraged crypto trading on DEXs for example? (In the limit of high leverage, this reduces to gambling.)

I'm interested in *gambling addiction*... (...in addition to being a staunch libertarian, in favor of personal sovereignty.) ----- What do you think of a law like this: * Each year, each person is allowed to **cap** their total $ gambling losses for **next year**. In other words, in 2026, you could register online (with the govt) such that in 2027 you could not lose more than $500. Then, casinos, DraftKings etc, would be forced to cut you off, after you lost $500 (in 2027). They'd have to cut you off until Jan 1 2028. Or -- they'd have to let you play for free, I guess. Just trying to be creative here. What do you think? Any problems? ----- One problem is: how do you define gambling? Is a Vanguard Index Fund, gambling? What about options and puts? What about SuperBowl squares? Plus, of course, any law-based solution, will send people into the Black Market. I've heard that most gambling profits (80%) come exclusively from the tiny minority (5$) of problem gamblers. So they obviously would fight this tooth-and-nail.

At the very very end of my giant essay you will find this: The "see also" links to his Brexit video Part 3 quotes David directly a few times I think my advice "have exactly two parties" is a little clearer than the argument in "choices" -- it is mostly taken from Shapiro's book However Shapiro's book asks a question (implied): "who owns these parties?" But it gives no answer - so I answered it.

A two-party democracy is best overall -- both for liberty and for everything else, but existing notions of democracy are quite misconceived, so it will probably take a long time for people to figure out why this is the case. It took me 150+ pages to explain it the first time, but now summarized in just 2 truthcoin.info/blog/democracy/

@leecronin We should be doing more abduction and less deduction and induction. Abduction drives discovery of novelty.

Discovery is unpredictable because novel ‘discoveries’ cannot be found from prior data in principle. The interface of the discrete past with the continuous future produces discovery. If you find a ‘discovery’ deducible from your data then by definition it isn’t a discovery.

Hi Alex I believe the biggest leverage in know-how would be in mathematics because of the application to AI-assisted algorithm discovery (AlphaEvolve, etc). See here for details x.com/Dr_JohnFletche… Regarding trying different data types, yes, I feel it would be healthy to have a diversity of approaches. That's why its odd that there's not a single company, startup or hyper scaler, talking about capturing and utilising know-how.

Hey @Dr_JohnFletcher - Aren’t the two views pretty aligned? You’re saying there’s still a ton of process/knowhow left to capture from humans, and the paper’s all about iteration + experience getting us past today’s data wall. Does this actually make the case for chasing *different* data types *and* multiple approaches at once, instead of betting everything on pure RL/self-generated stuff? Curious where you see the biggest leverage still hiding in human knowhow.

Multi-billion dollar investment rounds continue to be raised based on the following assumption.. "In key domains such as mathematics, coding, and science, the knowledge extracted from human data is rapidly approaching a limit. The majority of high-quality data sources — those that can actually improve a strong agent's performance — have either already been, or soon will be consumed." Quote from "Welcome to the Era Of Experience" google.com/search?q=Welco… And yet, the assumption is false. This is not just my opinion, it's been demonstrated and accepted as uncontroversial for decades In mathematics, for example, most knowledge exists in the form of "knowhow", and there are already large-scale efforts underway to capture it x.com/SAIRfoundation… So what's going on? In this article, I explain x.com/Dr_JohnFletche… @sequoia @RichardSSutton

Google DeepMind veteran David Silver just launched a London AI lab Ineffable Intelligence, and raised $1B at a $4B valuation, bets on radically new type of Reinforcement Learning to build superintelligence. Silver’s core argument is that large language models — the architecture behind ChatGPT, Claude, Gemini and every major AI system in commercial use today — are fundamentally limited. They learn from human-generated data. They can synthesise, summarise and extend what humans have already written or thought. But they cannot, in Silver’s view, discover genuinely new knowledge. Ineffable Intelligence aims to build what Silver has described as “an endlessly learning superintelligence that self-discovers the foundations of all knowledge.” The approach is rooted in reinforcement learning — the branch of AI Silver has spent his entire career advancing. --- the-decoder. com/deepmind-veteran-david-silver-raises-1b-seed-round-to-build-superintelligence-without-llms/

" fundamentally it should be totally possible." Andrej Karpathy on a distributed PoW auto-research network. He is absolutely right. @tigfoundation has had this exact system live since 2024 (and added the missing piece: price discovery)

This week, Andrej Karpathy independently described TIG without being aware of its existence. @dr_johnfletcher’s reply quickly became- by orders of magnitude - our most viral post ever. Today at 5PM GMT, join the good Doctor and @0x_Asuka as they discuss what this means for TIG and science as a whole.

@everythingLLM Hi, I'd say every component is make or break. Everything is needed. WRT dual licensing, this post has more detail x.com/Dr_JohnFletche… Happy to hear your feedback.
John Fletcher (𝔦, 𝔦)@Dr_JohnFletcher

Hi Sebastian, Thanks for your engagement. In my view, the issue with traditional dual licensing is not well described by the word "complexity." For example, the conceptual complexity of understanding two licences (lets say its GPLv2 and something like MIT) one of which you can use if you are willing to pay, is low. I fell it’s more accurate to say that dual licensing creates a tension between the commercial interests and the collaborative norms of open source development, and that this tension can result in the suppression of community contributions. Of these tensions, the most insoluble has always been the tendency for perceived injustice when monetary compensation for contributors available/necessary, and this was necessarily centrally-determined (by the vendor). The solution, in the context of open source, was in fact identified by Eric Raymond 25 years ago: a market mechanism for pricing contributions econ.ucsb.edu/~tedb/Courses/… This works because a market is an impersonal allocation mechanism (Hayek), and avoids creating tensions that otherwise result from centrally-determined (intentional) allocation. In TIG the “utility” of the proof of work is the market signal generated by the miners (the “Benchmarkers”) choice of algorithm. This signal allows us to address a market failure in the pricing of algorithms and achieve a market distribution of rewards to the contributors of the algorithms (the “Innovators”).

@Dr_JohnFletcher The dual licensing model is the make-or-break piece. Open source with commercial licensing is clever, but it requires companies to actually care about the algorithmic edge. Is there early evidence that commercial adopters are paying?
