<p>> if you just prompt the AI and believe what it tell you then you have AI psychosis<p>This is the right definition. LLM outputs have undefined truth value. They’re mechanized Frankfurtian Bullshiters.  Which can be valuable! If you have the tools or taste to filter the things that happen to be true from the rest of the dross.<p>However! We need a nicer word for it. Suggesting someone has “AI psychosis” feels a bit too impolitic.<p>Maybe we reclaim “toked out” from our misspent youths?<p>e.g. “This piece feels a little toked out. Let’s verify a few of Claude’s claims”</p>

<p>One can't help but observe the contrast between counterparty behavior here vs. the crypto boom.  A counterparty service had a secret worth 400K in-hand and just passed it back to the user. Meanwhile crypto worries about MEV, the Dark Forest, etc.<p>This cycle is hostile in lots of ways, but the trustworthiness and absence of hostility in this dimension is quite nice.</p>

<p>You may want to take a look at `man ed`, `info ed`, or [0]. ed is many things, but verbose is not one of them.<p>In particular, it's designed for the teletype era, when (a) the user would have a trace of all the commands they'd sent and output they'd received, since it was literally printed on paper, and (b) output was literally printed on paper, and so had a direct, non-negligible cost.<p>This is more or less exactly the situation LLMs find themselves in.  they can attend to ~all the prior output in their context window, but there's a direct cost to adding new symbols to context.<p>We've got a tool for exactly that setting, so it would be fun to try it!<p>[0]: <a href="https://en.wikipedia.org/wiki/Ed_(text_editor)" rel="nofollow">https://en.wikipedia.org/wiki/Ed_(text_editor)</a></p>

<p>Only sort of related, but I would love to see a harness with ed as the primary file editing / reading tool. Half the bash Claude runs seems to be sed anyway, having some state persist in ed would seem to help.<p>What does one do when a full editor consumes too much bandwidth^H tokens? Use ed, the standard editor!</p>

<p>> Professional formatting, length, and clear prose are no longer indicators of care and work quality (they never were, but in the past, if someone drafts up a twelve page spec, at least you know they care enough to spend a lot of time on it).<p>I feel the loss of this signal acutely. It’s an adjustment to react to 10-30 page “spec” choc-a-block with formatting and ascii figures as if it were a verbal spitball … because these days it likely is.</p>

<p>Trying to buy a single barrel of oil <> getting assigned on a futures contract.  An assigned long isn't getting a physical barrel either, they're transferring into a pipeline/storage facility/truck.<p>You're right that your broker will do all they can to avoid you shooting both you and them in the foot.  But your agreement with your broker does not control your relationship with the counterparty to your futures contract.  If the broker doesn't (or can't) close your position in time you('re both) on the hook.</p>
