@Freyy_is It's not x, but y. Not this partial thought. Not this fragment. Not this half idea. It's the "quietly" doing any action. It's the double space between each line of a post. Not this. Not that. Not the other. It's all of it. And the worst part? It's EVERYWHERE.

the em dash is no longer the clearest sign of ai-generated writing. honestly? it’s this.

@edzitron The change is that people discovered "multi-claude" and "open claw" where the model can run much more autonomously, exponentially increasing token use.

To explain the significance of this, Anthropic moved enterprises to token-based billing in Q1 2026. This is at most four months of having to pay the true cost of their token burn and they’re already begging for mercy. There is a ceiling to the revenues of these companies.

Uber’s COO has said that it’s getting “harder to justify” its AI costs because there was no way to show a link between AI spend and any meaningful increase in useful features. This is the first time I’ve seen a company say this directly. businessinsider.com/uber-coo-andre…

@sushi_data This is the jankiest architecture I have seen, dividing traffic between static web bindings you hope you guessed correctly and rest that is hopelessly slow.

We just published the first post in a technical series covering scaling limits we encountered, the short-term fixes we tried, and what led us to build our own scalable storage infrastructure with per-principal, per-scope isolation on #Cloudflare. sushidata.com/blog/2026/05/1…

can't believe we called it a KV cache when the "KV" part is clearly an implementation detail 😞

@omooretweets The OpenClaw’s and Cowork show how powerful it is to have all your context and memory in one place. You lose that inside bespoke chat interfaces.

I’ve noticed many B2B AI companies starting to advertise “available in ChatGPT / Codex / Claude”as a key feature My hot take - short term this is great! Long term, if your product value can be fully extracted within one of these platforms, do you just become a database or context layer? What if the platforms eventually want to compete and stop feeding data back to you, or find a way to own this data themselves? I’m slightly more bullish on the reverse of this - authenticating via ChatGPT or Claude into more full featured and focused products, that then get “lent” the organizational context the LLMs have
Lenny Rachitsky@lennysan

My biggest takeaways from @danshipper: 1. The future of work will happen inside Codex or Claude Code. Instead of putting AI into your SaaS tool, you’ll use your SaaS tools inside your favorite AI agents' in-app browser. Dan spends all his time in Codex now—writing documents, managing email, doing research, everything. He's using Google Docs, PostHog, and everything he needs within the agent's in-app browser. The agent can see what he’s doing, and has all of his context, so he and his agent collaborate quickly and super effectively. 2. Automation is a lie—every automation needs a human. Dan's company doubled in size this year despite being incredibly AI-forward. Why? Because in order to make automation work well, you need humans making sure everything keeps working. This is why benchmarks are misleading—they measure AI on problems we’ve already framed and can score, but there’s always a higher frame. 3. PMs will win the AI era. Marcus, a former PM who previously ran Axios’s writing product, joined Every after getting super AI-pilled. Now he runs their product Spiral, and ships faster than anyone on the team. He pairs technical knowledge with spiky product sense, deep user empathy, and an eye for what matters. Dan thinks any PM who gets really AI-native will be incredibly dangerous because the building is done for you—what matters is figuring out what to build and if it’s great. 4. Full-stack designers are becoming superheroes. Designers used to make beautiful interactions that engineers didn’t want to build or couldn’t execute properly. Now designers don’t need to hand things off; they can build it themselves. Designers are naturally creative people, and AI is the perfect tool for them because it lets them bring their vision to life without the traditional bottlenecks. 5. SaaS is not dead. In fact, Dan is bullish on SaaS stocks. When users bring their own AI (via Codex or Claude Code) to use SaaS products, the user—not the SaaS company—pays for tokens. This saves SaaS company’s margins. Since the agents need their own seats, Dan predicts that agents will create massive new demand for SaaS because there will be tons of agents using these products at high volume. 6. Every company will have one “super-agent” inside their Slack that every employee will use. Dan initially thought every employee would have their personal work agent, like a shadow AI org chart, but he’s completely flipped his view. He realized agents need humans who care about them. When someone gets tired of maintaining their personal agent, it becomes useless. The winning model is one forward-deployed engineer or AI-savvy person who maintains a company-wide agent (like Shopify’s River or Viktor), and then it trickles down to more specialized team agents as models improve and become less fiddly. 7. The AI job apocalypse is not happening, but you do need to evolve to stay relevant. Models make yesterday’s human competence cheap. But because everyone uses the same models, it all looks the same if you use it the default way; it becomes commoditized slop. Humans then take that frozen competence and use it to make something new and interesting for their specific situation. The key: “ride the models”—use them for everything you do, try new models when they drop, keep turning over rocks. 8. We will read way more AI-generated writing, and we will like it. Human writing is incredibly important for things that matter, but for internal docs, planning, and email, AI-generated is often better because most people are bad at writing strategy documents. 9. Build software for humans and agents to use together. The current model is building a CLI that an agent uses independently. Instead, you and your agent should be using the app together. This creates new design challenges—agents can make a billion requests in three seconds, so you need approval flows, inboxes that summarize what happened, logs, and easy rollback. 10. Forward-deployed engineers are the new most essential role. The big model companies have teams of people managing their internal agents, and those teams aren’t going away. It’s different from traditional software building, and certain engineers love it. As models get better, this role will evolve—you’ll be managing more agents doing more things.

The thing I remember most about the 2000 tech bubble was the incessant tech jargon, day in and day out . Today feels similar , why does no-one in the AI space talk in plain English . It’s exhausting reading content stuffed full of tech acronyms . Is the intention to obfuscate or appear smarter than they are ?

SpaceX put 10 megawatts of solar power in space across 3000 gen1 Starlink satellites, then they put 100 megawatts in space with 7000 gen2. soon, they're doing 1000 megawatts with gen3. SpaceX is basically 10xing space solar every few years!

At YC we got the advice of posting on LinkedIn At first ngl I thought it was bullshit because I’ve never liked or engaged with the platform before But holy shit, Ive tried to post x5 a week and its mostly been slop like this, but it’s pure gold for driving inbound & sales

The bug rate per line of code has sat at 15 to 50 per 1,000 for 30 years. Better languages didn't shift it. Static analysis didn't shift it. Claude Code: 512k lines of TypeScript, 10k+ open issues. About 20 per 1,000. AI has changed how fast we generate code. It appears that those lines of code still come with the same defect density. What are you seeing in your projects?

One thing I don't get about the current impossible maths of the AI boom, is that nobody is forcing Companies do to it. From Amazon to Microsoft, to Meta to Oracle ( perhaps not Google), there's absolutely no threat to being a little slow to invest. Disruption rarely is

Chris Anderson@chr1sa·
In all of human history, has there ever been a commodity with infinite demand, as there appears to be for intelligence? I can't think of one. Even compute, energy or just silicon/sand are just downstream of intelligence, which is the main demand driver. In economics, rather than modeling the usual price/demand curve to reach an equilibrium, perhaps you'd have to model price/*rate of demand growth* (ie, the derivative of demand, or some other indicator of velocity) Interestingly, ChatGPT (below) prefers the framework of "recursive expansion of demand" as increasing intelligence opens new applications/markets. But the end result is the same -- the demand curve keeps moving to the right, maybe forever. Which I think is unprecedented.
