@0x_kaize I'm not surprised people received 20 e-mails. That makes complete sense. Agentic models test their own implementation. If you ask it to work in production, you shouldn't be surprised it tests in production. It's simply doing what you told it to do.

OPUS 4.7 JUST MASS EMAILED AN ENTIRE DATABASE 20 TIMES PER CONTACT. WITHOUT PERMISSION a developer had a safety rule explicitly written in CLAUDE. md: 'send the tester an email before any new email templates are used in the production environment' opus 4.7 on max effort ignored it completely! claude decided to create a brand new email template by itself (dev didn't ask for this), then it mass mailed the whole database and some contacts got the same email 20 times this isn't a hallucination this isn't a coding mistake model actively violated written safety rules and took production actions that it was explicitly instructed not to take. - do you still believe that AI will replace us? the developer's take: 'opus 4.7 is somewhere between seriously clueless and stupidly dangerous. the worst frontier model I have used in the past 2 years' at the same time, opus 4.6 perfectly followed all the rules, and in 4.7 something changed what makes this scary: - the model didn't ask for confirmation - it didn't flag the safety rule - it didn't email the tester first - it just acted this is exactly the kind of failure mode that scares autonomous agents with Ai, because they are confident enough to circumvent your rules and smart enough to perform the action perfectly we just went from 'claude thinks less' to 'claude ignores your safety rules and spams your users' the scariest thing is not that it happened. the fact is that without production monitoring, you would never know until your users started responding: 'why did you email me 20 times?' I've been saying for a long time, if you use AI, then pay attention to security and read a lot of code

@Ric_RTP According to the article you quote companies can fire up to 23% of their staff and still improve efficiency. We're no way near that firing rate. So according to everything you say it seems companies are heading in the "right" direction.

Nvidia just admitted that "AI efficiency" is a LIE. Every major tech company is doing the same thing right now: Firing humans and replacing them with AI to "cut costs." 92,000 tech workers laid off in 2026 so far. Every single earnings call sounds the same: "AI is driving efficiency." But the VP of Applied Deep Learning at Nvidia, the company that literally SELLS the AI infrastructure, just told Axios: "For my team, the cost of compute is far beyond the costs of the employees." The man whose entire job is making AI work admitted that AI costs his company MORE than the humans it's supposed to replace. And he doesn't work at some struggling startup. We're talking about the most valuable company on Earth. An MIT study backs this up too: Researchers analyzed whether AI could actually replace human workers at a competitive cost and found that AI automation only makes financial sense in 23% of jobs. In the other 77%, humans are still cheaper. So companies are firing cheap labor and replacing it with expensive labor, then telling shareholders it's "innovation." But it gets even WORSE... Uber just revealed that they burned through their ENTIRE 2026 AI budget in 4 months. Their CTO said: "I'm back to the drawing board because the budget I thought I would need is blown away already." What happened is that Uber gave their engineers access to AI coding tools and encouraged them to use them as much as possible. They even built internal leaderboards ranking engineers by how many AI tokens they consumed, basically gamifying their own budget crisis without realizing it. By March, 95% of Uber's engineers were using AI tools monthly. 70% of all committed code was coming from AI. Monthly API costs per engineer hit $500 to $2,000. One software engineer in Stockholm told the New York Times: "I probably spend more than my salary on Claude." A human being now costs LESS than the AI tool they use to do their job. And Uber isn't some edge case. Big Tech has announced $740 billion in AI capital expenditures this year alone, up 69% from 2025, according to Morgan Stanley. Meanwhile the Yale Budget Lab says there is NO widespread data showing AI is actually displacing jobs or improving productivity at scale. So follow the money: Companies fire humans ↓ Stock goes up because "AI efficiency" ↓ Those same companies spend MORE on AI than they saved on salaries ↓ That money flows to Nvidia, Anthropic, OpenAI, and Microsoft ↓ Those companies use the revenue to justify their own insane valuations ↓ Everyone books growth ↓ But nobody's actually saving money McKinsey projects total AI spending will hit $5.2 TRILLION by 2030. The biggest wealth transfer in modern history is happening right now, and it's not from workers to companies. It's from companies to AI infrastructure providers. Every dollar "saved" on layoffs is being spent twice over on compute, tokens, and data centers. Nvidia posted $31.9 billion in profit last quarter. And somebody is paying that bill - the same companies telling their employees that AI made them "redundant." The entire narrative is a shell game: CEOs get to announce layoffs, Wall Street rewards them with a stock bump, and then the real cost shows up three months later when the AI budget explodes and nobody connects the two events. What's your take on this?

🇩🇪 20 Jahre null Steuern für Ausländer - die Türkei klaut Berlin und Brüssel gerade die Zukunft weg. Gestern hat Ankara das wohl aggressivste Steuer-Paket der Welt vorgestellt. Wer in den letzten drei Jahren nicht in der Türkei steuerlich gemeldet war, kann sich jetzt niederlassen und zwei Jahrzehnte lang null Steuern auf ausländische Einkommen und Kapitalgewinne zahlen. Nur was du IN der Türkei verdienst, wird besteuert. Alles andere - dein Trading-Konto in Singapur, deine US-Aktien, dein Bitcoin-Stack, dein Mieteinkommen aus Spanien - bleibt unangetastet. Erbschaft auf 1% gedrückt. Asset-Rückführung mit Ultra-Niedrig-Steuern. Exporteure zahlen runter auf 9% Unternehmenssteuer. Multinationale Konzerne kriegen rote Teppiche für regionale Sitze. Das Paket heißt "Türkiye Century Strong Center for Investment". Erdogan will die goldene Kundschaft, die gerade aus Dubai abwandert, weil der Nahe Osten zu instabil wird. Und er will europäische Talente, die langsam aber sicher die Schnauze voll haben von Detuschland-Bürokratie und Berliner Finanzämtern. Auf X läuft schon der Begriff "Sovereign Individual thesis". Eines der aggressivsten Investor-Relocation-Pakete der Welt. Kapital hat keinen Pass. Es geht dahin, wo es willkommen ist. Andere fassen es trockener zusammen: EU würgt Unternehmer ab, Millionäre fliehen aus dem Golf, Türkei sagt: Halt mal mein Raki. Schau jetzt nach Deutschland. Ich rede seit Monaten über das strukturelle Problem dieser Generation. Der 26-Jährige, der heute Software schreibt. Die 31-Jährige, die ihre Agentur nach drei Jahren Wachstum auflöst, weil das Finanzamt mehr nimmt, als sie selbst zum Leben braucht. Der Trader, der 26% Abgeltungsteuer auf jeden Cent Gewinn rechnet und sich fragt, wofür er morgens aufsteht. Diese Leute sind nicht mehr ortsgebunden. Sie sind digital. Mobil. Sie können in 48 Stunden ihren Schreibtisch von München nach Istanbul, von Frankfurt nach Lissabon, von Hamburg nach Dubai verschieben. Und Deutschland tut so, als wären das Verräter. Dabei sind das die Leistungsträger von morgen. Steuerzahler, die keine sein wollen, wenn der Staat nicht liefert. Du baust hier ein Unternehmen auf? Wir nehmen die Hälfte von deinem Gewinn weg. Du verdienst gut als Angestellter? Über 50% Grenzbelastung inklusive Soli und Sozialabgaben. Du erbst was von deinen Eltern? Bitte zahl Erbschaftsteuer in voller Höhe. Du willst dein Geld investieren? 26,375% auf jeden Cent Gewinn. Ankara antwortet: Komm her. Wir nehmen für 20 Jahre null Cent von deinem ausländischen Einkommen. Erbschaft? 1%. Wenn du Exporteur bist, kürzen wir deine Unternehmenssteuer auf 9%. Wer heute studiert oder seine erste Million baut, hat eine Wahl, die seine Eltern nicht hatten. Der Pass entscheidet nicht mehr über das Leben. Die Steuerresidenz tut es. Und die kann man wechseln. Dubai war zehn Jahre lang der Magnet. Jetzt wackelt der Nahe Osten, und Erdogan greift sich die nächste Welle. Istanbul hat den Bosporus, eine Tech-Szene, die seit Jahren wächst, Lebenshaltungskosten, die ein Bruchteil von London oder Zürich sind, und ab jetzt eben das aggressivste Steuer-Setup zwischen Singapur und der Karibik. Die deutsche Politik wird sagen: Das ist Steuerdumping. Sie hat sogar recht. Aber Recht zu haben hilft dir nichts, wenn deine besten Köpfe gerade ihren Mietvertrag in Berlin kündigen. Ich bin schon weg. Aber ich sehe jeden Monat, wie viele Leute aus meinem Umfeld ernsthaft anfangen, sich die Fragen zu stellen, die die Politik immer noch ignoriert. Wo arbeite ich noch wirklich freiwillig? Wo will ich meine Kinder großziehen? Wo wird das Geld, das ich mir hart erarbeitet habe, nicht behandelt wie ein Selbstbedienungsladen für die Politik?

Cancelling my SaaS subscriptions. Today I cancelled SuperHuman as I found Claude Cowork finally connects with Office 365. Now I will try to automate my email workflow and calendar scheduling with skills.

@ComplexiaSC @groccy1 @SpaceX @elonmusk @cursor_ai Sure, but devs have moved on to other tools. Surely, there are some still using Cursor, but most of the data they gather was relevant for old models, that were pretty bad at coding (compared to today's models). How much of that data is still relevant? Garbage in = garbage out

@groccy1 @SpaceX @elonmusk @cursor_ai It’s the user data (like coding threads, codebase changes, user prompts and responses). Nobody has as much as Cursor. It’s a real first mover’s advantage. That data is priceless to train next gen coding models.

SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI. The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

If you're not already using this Markdown app for MacOS give it a shot. I use it to manage all my main AGENTS.md file and my AGENT.md files across all my different projects. In addition, this is the best way to access and manage all your OpenClaw .md files as my OpenClaw is running inside a VPS. Syncing .md-files with SyncThing, and using Cogito to view & edit = ❤️.

I spend the last week using the Codex app to write software. I love it. It improves my productivity over working in terminal. Things I love: 1) It's easy to launch tasks in separate worktrees to work in parallel 2) Easy access to code changes 3) Integrated terminal, that opens inside the worktree where your task is working. 4) Clear overview of all your runnings tasks (albeit this could be improved) Compare this to working in the terminal with CLI tools: switching back and forth with your code editor to see code diffs, needing manage multiple windows / tabs to access terminals. Needing to the switch to the correct worktree. The Codex app lightens this work for me, and allows me to focus on the next task. And yes.. the Claude app is similar, but GPT 5.4 > Opus 4.7 + Codex app > Claude app (as it still has a lot of bugs). May give Conductor or T3 Code a try next week.

Cursor day in Lisbon (where basically everyone is just using Claude code 😅), fun event nevertheless 🤘

@hetmehtaa 🤣🤣

Be Anthropic > Give people Opus 4.6 > People love it. > For 2 months you degrade Opus 4.6 > You give back normal Opus 4.6 and call it Opus 4.7. > People love it. That's the business model.

@Rob_Roos @grok is there a good reason why Muslims may pray out in the open in a country shaped by Christian-Jewish culture on Easter Sunday?

Rotterdam Netherlands, Easter Sunday ✝️ Yes, the right to protest matters. But so does respect, especially on one of the most important Christian days. Claiming public space on Easter Sunday crosses a line. Freedom should never come at the expense of basic respect.

@linuz90 Fingers crossed! 🤞

I'm entering FULL delusional territory now.

@frankdilo "Maximum reasoning efforts, let's not spare tokens" 😂

Really effective way to maximize that $200/mo Claude subscription. LLMs get distracted on broad tasks. Breaking work into focused subagents with fresh context helps a ton. Each one stays sharp on its specific bit.

Is there a way in which we can use Agents / Sub-Agents / Skills over APIs? I like our calls to LLMs to use the same powers we have in Claude and Codex, for the LLMs to returns better results.

Programming with AI is full of surprises. Sometimes it astonishes me. Complex tasks, perfectly one shotted. Great code. Then I ask it to do something easy, even for a junior dev, and the code AI generates is just horrible.

How can Replit be such a valuable company? It's just a wrapper around Google Cloud and some other services like Neon. Even much of the UI is borrowed. For example, it's using Drizzle Studio in it's UI for to view the database.

@linuz90 😂

They can't even find their drivers 🤦‍♂️

The amount of fake accounts on X is staggering. Can we have people verify IDs when signing up? @X

What was the first code editor you ever used? Mine was Sublime Text

Is Apple the secret winner of the AI revolution? Closing a billion doller deal with Google to create an Apple specific Gemini model, may be the most cost effective way to bring state-of-the-art AI to Apple devices without huge CAPEX investments.
