<p>This post sets up a straw man from the outset, and only gets worse from there.<p>I understand how we got here, where many experienced programmers, managers, and bloggers only know capital-A Agile as the watered down version sold via certifications, crummy medium posts, and atlassian flavored kanban boards. But that isn't agile.<p>I can’t even with the pitch into spec driven development as some sort of high watermark of software methodology.</p>

<p>Wow. So much hate in the comments here. Of all the funding / equity events lately, I wonder how this one gets so much doubt and distrust from the start.<p>If this isn’t something to at least root for, in the sense of a small team, novel product,  serving a real need, then I dunno what is. You can use jj or tangled and still appreciate improvements to git and vcs on the web in general. Competition amongst many players is a good thing, even if you don’t believe in this one particular vision.<p>Heaven forbid it isn’t 100M going to a YC alum for yet another AI funding raise.</p>

<p>This has been the case for 15-20 years at least. It’s only now that the horrible experience for regular users is so obvious compared to Linux becoming quite good, and Mac OS ranging from fine to meh.<p>The continual recall/ai push from Microsoft has not helped at all and is pretty gross. There is a way to do a “recall” style thing that some folks will really want if they can trust it. The msft approach has been the opposite of that.</p>

<p>Yes. This. Too little too late MSFT.<p>And it really comes down to $MSFT. If the stock keeps dropping, how long do you think any real commitment to “quality” for a boring, low(no?) revenue product will last? Very little when the ad/partner revenue really starts flowing for “ai focused metrics” that can directly tie to windows surveillance (ie recall).</p>

<p>I’ve found LLM development expands the scope of what I can do to an absurd level. This is what exhausts me.<p>My limits are now many of the same things that are have always been core to software dev, but are now even more obvious:<p>- what is the thing we are building? What is the core product or bug fix or feature?<p>-  what are we _not_ building? What do we not care about?<p>- do I understand the code enough to guide design and architecture?<p>- can I guide dev and make good choices when it’s far outside my expertise but I know enough to “smell” when things are going off the rails<p>It’s a weird time</p>

<p>Codex does something sorta magical where it auto compacts, partially maybe, when it has the chance. I don’t know how it works, and there is little UI indication for it.</p>

<p>No. Nope. Agents do just fine with all sorts of CLIs. Old standards, new custom stuff, whatever.<p>The CLIs I’ve seen agents struggle with are those that wrap an enormous, unwieldy, poorly designed API under one namespace. All of Google Workspace apis, for example.</p>

<p>he favors Codex?<p>The original name of his ai assistant tool was 'clawdbot' until Anthropic C&D'ed him. All the examples and blog posts walking thru new user setup on a mac mini or VPS were assuming a claude code max account.<p>I know he uses many llms for his actual software dev.. - right tool for the job. But the origins of openclaw seem to me more rooted in claude code than codex.<p>Which does give the whole story an interesting angle when you consider the safety/alignment angle that Anthropic pledges to (publicly) and OpenAI pretty much ignores (publicly). Which is ironic, as configuring codex cli to 'full yolo mode' feels more burdensome and scary than in Claude Code. But I'm pretty sure that speaks more to eng/product decisions, and not CEO & biz strategy choices.</p>

<p>> But on the nuclear issue, it's not a good sign that he's explicitly saying that this AGI future is a threat to nuclear deterrence and the triad. Like, where do you go up from there? That's the highest level of alarm that any government can have. This isn't a boy crying wolf, it's the loudest klaxon you can possibly make.<p>This is not new. Anthropic has raised these concerns in their system cards for previous versions of Opus/Sonnet. Maybe in slightly more dryer terms, and buried in a 100+ page PDF, but they have raised the risk of either<p>a) a small group of bad actors w/ access to frontier models, technical know-how (both 'llm/ai how to bypass restrictions' and making and sourcing weapons) to turn that into dirty bombs / small nuclear devices and where to deploy them.
b) the bigger, more scifi threat, of a fleet of agents going rogue, maybe on orders of a nation state, to do the same<p>I think option a is much more frightening and likely. option b makes for better scifi thrillers, and still could happen in 5-30ish(??) years.</p>

<p>Also many CLIs act differently when invoked connected to a terminal (TUI/interactive) vs not.  So you’d run into issues there where Claude could only test the non-interactive things.</p>

<p>Is there a term for AI-fueled dev psychosis? "AI architecture astronaut" ? There should be one if not. Or maybe just AI-fueled hucksterisim...<p>I recognize 100% that a tool to manage ai agents with long term context tracking is going to be a big thing. Many folks have written versions of this already. But mashing together the complexity of k8s with a hodge podge of lotr and mad max references is not it.<p>Its like the complexity of J2EE combined with AI-fueled solipsim and a microdosing mushroom regime gone off the rails. What even are all the layers of abstractions here? and to build what? What actual apps or systems has this thing built? AFAICT it has built gas town, and nothing else. Not surprising that it has eaten its own tail.<p>The amount of jargon, ai art, pop culture references, and excessive complexity going on here is truly amazing, and I would assume its satire if I didn't know Yegge's style and previous writings. Its like someone looked at the amount of overlapping and confusing tools Anthropic has released around Claude Code, and said "hold my beer, hand me 3 red bulls and a shot of espresso, I can top that!".<p>I do think a friend of mine nailed it though with this quote:
"This whole "I'm using agents to write so much software" building-in-public trend, but without actually showing what they built, reminds me of the people selling courses on stock trading or drop shipping."<p>The amount of get-rich quick schemes around any new tech are boundless. As yegge himself points out in the post towards the end, you'd be surprised what you can pull off with a ridiculous blog post, big-tech reputation, and excessive LOC dev-tools in a hype-driven market. How could it be wrong if it aligns so closely with so many CEOs dreams?</p>

<p>The performance of hardware today is even more mind-boggling compared to what most people (SRE managers, devs, CTOs) are willing to pay for when it comes to cloud compute.<p>even more so when considered in the context of dev 'remote workstations'. I benchmarked perf on AWS instances that was at least 5x slower than an average m1 macbook, and cost hundreds of dollars a dev per month (easily), and the macbook was a sunk cost!</p>
