<p>So actually I've been testing this — it seems to be useful in limited cases. LLMs have gotten so good now that a properly defined spec is no worse than a spec + property based testing.<p>I still found it useful for<p>1. trusting a bit of code is correct<p>2. rule-dense bits of code (eg something like a date parser)<p>The real issue so far is that I'm having trouble finding tasks where an LLM can't correctly code up an exhaustively defined spec.</p>

<p>Nice! It's interesting to see quantitative ways of measuring slop. I'm curious what _would_ happen if you did plug these back into the LLM as a form of feedback. Goodharting may happen... or it could get the LLM to generate cleaner code potentially?</p>

<p>I find that it's difficult to thread the needle of navigating on my own with also not spending forever in traffic or in train delays. It's disheartening when I do know how to get somewhere, but I land in a +1 hour traffic jam because I chose to not look at GPS.<p>Maybe I need an app that just yells at you when you take a super-wrong turn, or if you're about to be in a massive amount traffic?</p>

<p>I've always found it a bit surprising that we don't all celebrate smallpox elimination day. I think it'd be a great reminder of the victories that humanity has had against the four horsemen.</p>

<p>As other commenters noted — Rome did almost fall apart and come back a few times. Peter Brown has a bit about how the crisis of the 3rd century was reversible because it was fundamentally about control of the empire, rather than disassembling it.<p>My headcanon is that while the elites of the empire found more value in controlling the reins of power rather than carving out their own fief — that's what prevented collapse.</p>

<p>Yeah, that's a good point. Even though Latin had diverged to the point that reading Cicero required explicit schooling — the post-476 Romans did consider themselves Roman and fully the descendants of the late Republican / early Imperial period.<p>I'm mostly arguing that people overindex on the political changes and don't see the ground level continuity. Map color changed != they're not Roman any more.<p>Regardless, I do enjoy asking "what made Rome Rome?" — I like the idea of the Byzantines being Roman in 1453 even though at that point it was tenuous.</p>
