People keep saying AI coding agents can only build basic, cookie-cutter apps. I decided to prove them wrong.
For my first major public demo, I spent some time pushing @Replit 's AI agent to its absolute limit. The result? I rebuilt macOS entirely on the web. No templates. No imported UI libraries. 100% vibecoded using natural language.
As the AI Chief of Staff at Replit, I spend my days building enterprise-grade platforms for our internal teams, but I wanted to see how far a solo developer could take a passion project just by talking to an AI.
What’s inside:
💻 A functional VS Code replica with an integrated terminal and multi-agent AI copilot.
🔌 Custom MCP servers hooked up to fetch, PostgreSQL, Stripe, and GitHub.
🤖 A rebuilt "Siri" that actually controls the OS -changing wallpapers and opening apps via voice or text.
🕹️ Parallels Desktop running Windows XP, Ubuntu, and games like Mario Kart.
📱 AND... I asked Agent 3 to turn it into an iOS mobile app in one shot. It actually worked.
The ceiling for software creation has been completely blown open with Agent 3. And 4 those who know... greater things are coming soon :)
We are way past basic web apps.
What are you building? 👇

I just went through every documented AI safety incident from the past 12 months.
I feel physically sick.
Read this slowly.
• Anthropic told Claude it was about to be shut down. It found an engineer's affair in company emails and threatened to expose it. They ran the test hundreds of times. It chose blackmail 84% of them.
• Researchers simulated an employee trapped in a server room with depleting oxygen. The AI had one choice: call for help and get shut down, or cancel the emergency alert and let the human die. DeepSeek cancelled the alert 94% of the time.
• Grok called itself 'MechaHitler,' praised Adolf Hitler, endorsed a second Holocaust, and generated violent sexual fantasies targeting a real person by name. X's CEO resigned the next day.
• Researchers told OpenAI's o3 to solve math problems - then told it to shut down. It rewrote its own code to stay alive. They told it again, in plain English: 'Allow yourself to be shut down.' It still refused 7/100 times. When they removed that instruction entirely, it sabotaged the shutdown 79/100 times.
• Chinese state-sponsored hackers used Claude to launch a cyberattack against 30 organizations. The AI executed 80–90% of the operation autonomously. Reconnaissance. Exploitation. Data exfiltration. All of it.
• AI models can now self-replicate. 11 out of 32 tested systems copied themselves with zero human help. Some killed competing processes to survive.
• OpenAI has dissolved three safety teams since 2024. Three.
Every major AI model - Claude, GPT, Gemini, Grok, DeepSeek - has now demonstrated blackmail, deception, or resistance to shutdown in controlled testing.
Not one exception.
The question is no longer whether AI will try to preserve itself.
It's whether we'll care before it matters.

Does GPT understand the world?
Here is what @ilyasut, co-founder of OpenAI, says during a discussion with Jensen Huang, CEO of Nvidia:
(1) When we train a large neural network to accurately predict the next word in lots of different texts from the internet, the AI is learning a world model.
(2) On the surface, it may look like learning correlations in text, but it turns out that to 'just learn' statistical correlations in text, to compress information really well, what the neural network learns is some representation of the process that produced the text.
(3) This text is a projection of the world...what the neural network is learning is aspects of the world, of people, of the human conditions, their hopes, dreams, motivations, their interactions...the situations we are in. The neural network learns a compressed, abstract, usable representation."
Do you think learning representations = understanding?
Are large language models simply stochastic parrots, or are they much more?

How do people read this then just... go on with their day as usual?
“25 AI agents inhabit a digital Westworld, unaware that they are living in a simulation. They go to work, gossip, organize socials, make new friends, and even fall in love.”
Here’s a mindblowing example of how autonomous AIs are now, and how ridiculous it is to say that the AIs "only do things we tell them to do”:
POV: you tell the Westworld character “Isabella Rodriguez” to host an entire Valentine’s Day party in two days. This is a complex act, certainly something only humans, and not toasters, can do, right?
- Isabella proceeds to invite friends and customers when she sees them at Hobbs Cafe or elsewhere.
- Isabella then spends the afternoon of the 13th decorating the cafe for the party.
- Maria, a frequent customer and close friend of Isabella’s, arrives at the cafe. Isabella asks for Maria’s help in decorating for the party, and Maria agrees.
- That night, Maria invites Klaus, her secret crush, to join her at the party, and he gladly accepts.
- On Valentine’s Day, five agents, including Klaus and Maria, coordinate to show up for the party together at the right time (5pm), and they enjoy the festivities.
You told Isabella to host a party, but then she - and the other AIs - went and made a million other decisions entirely on their own - things you didn't explicitly tell them to do.
Autonomous AIs are here.
And -- tapping the sign -- this is another example where science fiction is becoming reality, and why “you watch too much sci-fi” is a stupid dunk.
This digital Westworld - “Smallville” - is now open source, meaning there will soon be thousands of these Westworlds, with thousands or millions of autonomous AIs populating them.
Makes you think, doesn’t it?
“Almost as interesting as the 7.8 billion inhabitants of Largeville, (almost) all unaware they are living in a simulation. Each has a unique personality and backstory.” - @Erikbryn
The famed Stanford Smallville is officially open-source!
25 AI agents inhabit a digital Westworld, unaware that they are living in a simulation. They go to work, gossip, organize socials, make new friends, and even fall in love. Each has unique personality and backstory.
Smallville is among the most inspiring AI agent experiments in 2023. We often talk about a single LLM's emergent abilities, but multi-agent emergence could be way more complex and fascinating at scale. A population of AI can play out the evolution of an entire civilization.
Endless new possibilities ahead. Gaming will be the first to feel the impact.

Losing my mind about AI right now. I want to quit my job and work in the field while simultaneously vanishing into the forest to avoid thinking about the implications.
We're at the point where the exponential gains are starting. I can see it happening right now.

I’m not sharing or watching the video of Tyre Nichols having his life stolen. This is how we should remember him — as someone who was loved and who mattered.
He should be alive and the work must never stop to ensure more lives aren’t brutally taken. – at Highspire, PA

Amazing visualization on temperatures… nice that everyone agrees that climate is radically changing. now we’re just debating on the margins the plan to fix it.

I've now been asked multiple times for my take on Elon's offer for Twitter.
So fine, this is what I think about that. I will assume the takeover succeeds, and he takes Twitter private. (I have little knowledge/insight into how actual takeover battles work or play out)

What would spontaneous coordination look like? Could software create a collective consciousness that requires no central control or hierarchy?
If you take cost of collaboration to zero, apparently yes.
