<p>Ok, then don't call it "instilling shame". Call it "creating a negative reward signal for deceptive behavior".<p>They absolutely lie and cheat. I recently had a problem where a process would die in a container. I told Claude to investigate. It came up with a hypothesis then I told it find a reproduction based on that. It spend many failed attempts until it found the "reproduction" to SSH into the container and `pkill` the process. Claude "knows" that this is cheating, because if I ask another instance to review that reproduction, it totally identifies that as nonsense.</p>

<p>But maybe you can instill properties like shame during training.<p>Models sometimes blatantly lie and cheat. In a social context, where actors remember, that might work the first time but you get penalized in subsequent tasks with loss of trust.</p>

<p>I'm not talking about model performance. I just mean the UX of Claude Code. I'm trying to use pi but there are so many paper cuts. Of course you can configure everything but that's a ton of work. Claude Code has pretty good defaults.</p>

<p>I'm switching to GPT because of this. The prose is so much more legible. The only reason I keep using Claude Code is because the harness is the best IMO.</p>

<p>Author here. I agree, I should add more hedging:<p>> Everyone knows you can tackle those with heuristics, but you don't (ALWAYS) have to sacrifice optimality<p>> We absolutely have tools that can (OFTEN) find provably optimal solutions in reasonable time</p>

<p>I've been hearing forever that latent reasoning is the next step. But none of the frontier labs seem to incorporate it. Any idea why? It doesn't sound so technically challenging. Sure you loose some interpretability but surely everyone would sacrifice that for a step-up in quality. Or at least offer a latent-reasoning-version of the model.</p>

<p>Fair enough but cutting the tax is another incentive measure: make the legal way to buy cigarettes the cheapest way. As the article states: the fact illicit tobacco is illegal does not prevent it and poses massive enforcement costs.</p>

<p>Another example: In Germany the chancellor decided that workers take too much "sick leave". Fair enough (probably) but they decided to clamp down on it by requiring a doctor's certificate from day one. Rookie mistake! For the doctors it piles on extra bureaucracy. Everyone who's actually sick is either miserable waiting in a doctor's office just to get some paperwork done or picks the lesser evil and goes to work sick where they infect the remaining colleagues.<p>An incentive based solution is: reduced pay on sick days. With _no pay_ you get sick people at work. With _full pay_ you get healthy people at home. With _reduced pay_ you can find a sweet spot. That adds no bureaucracy for doctors. For employers there is some but it directly translates into cost savings.</p>

<p>I know it's kinda beside the point but I like incentives compared to hard rules as a policy measure. They are much more effective, less bureaucratic and easier to push through. They are like weights vs. booleans.<p>Don't like smoking? Try out right banning it. It's impossible. You have to fight the lobbyist, the addicted consumers, the workers employed by the industry, ... Slapping a tax on it is much easier. A soft NO that's giving everyone time to adjust.</p>

<p>I don't disagree but for some of the examples given (YouTube, Instagram, X.com) a huge entry barrier is the network effect. Even if AI could perfectly clone these products in a day, that still doesn't translate to instant market share.</p>

<p>Ramen is a great soup. But I haven't been blown away in any shop not even Japan. EXCEPT that random place in Kyoto we went into without plan. I think it's even a franchise. Not an ancient shop with 100 year tradition or something:<p><a href="https://salmonnoodlekyoto.com/" rel="nofollow">https://salmonnoodlekyoto.com/</a><p>I got the "Salmon Dandan Noodles". Good lord that broth. No idea what was in there. It wasn't clear; rather slightly thick and creamy. And the salmon was so tender. I don't even like pork but I also ate that without thinking. Man I still miss that dish.</p>

<p>As always there is also the gradual sunset option: slap a tax on it and increase over time.<p>- That's easier to get past the lobbies.<p>- It still surfaces unexpected consequences but reduces impact.</p>
