I asked Simon Willison what the next leap in AI software engineering is likely to be. He explained the "dark factory" pattern where teams don't write any code or even look at their code.

Last week I sat down with Ankit and did a brain dump. 1. A software factory is essentially a CNC machine or a woodworking shop. Without training, many people will cut off their hands. 2. Building a true “dark factory” as fully automated software production with no humans in the loop means solving autonomous verification first 3. Code review was mostly broken even before AI happened. 4. Agent maintainability is replacing human maintainability as the real measure of code quality 5. Nobody Knows What Engineering Orgs Will Look Like 6. Programming Languages Will Converge, and the Next One Won't Be for Humans 7. The Craft Is More Important Than Ever

The software factory is already here. We're seeing bots write code, bots review it, and humans reduced to dispatching the next tool in the chain. Using 500k+ PRs from Code Review Bench, we looked at one question: can the human leave the loop yet?

Holy moly Never seen someone being that bullish for AI developement as Dario Amodei: - There's just an exponential just like we had an exponential with Moore's law - I think the models are just going to get more and more capable at everything - I've had internal people at Anthropic say, "I don't write any code anymore. I don't write I don't open up an editor and write code. I just let Claude code write the first draft and and all I do is edit it. - What what we're going to see in the future is just like we've going to be seen in the past except more so - the models are just going to get more and more intellectually capable and you know the the revenue is going to keep adding zeros. holy moly, Dario!

Anthropic CEO: “In the next 3 to 6 months, AI will write 90% of the code, and within 12 months, nearly all code may be generated by AI.” the job isn’t coding anymore, it’s telling machines what to build.

Insane: 90-95% of Claude Code is now written by Claude Code. I asked Mike Krieger (Anthropic's CPO) what changes when so much of your code is written by AI? His answer: The bottleneck moves from coding/design to: 1. Upstream: aligning the team around what to build. 2. Downstream: the PR merge queue, reviewing and merging all of the new code into production. Anthropic is where other product teams will be in a year or two, so it's important we pay attention. "I would expect that a year from now, the way that we are conceiving of building and shipping software changes a lot. Because it's gonna be very painful to do it the current way."

IN NEWS: Traversal launches out of stealth and raises $48M in seed and Series A funding. "With AI-written code, there’s going to be a Cambrian explosion. Most of it is going to be written by AI systems. It's going to get even harder to debug because we don't actually understand what's written." - Anish Agarwal "I think that (majority AI-written code) will throttle the use of AI software engineering tools because if I'm Head of Infrastructure I will think 'I don't trust this'."

Exclusive to X: I visit Factory's CEO Matan Grinberg to learn about the future of software engineering. San Francisco's best new AI developer tool. It isn't like Visual Basic of the past. For one, you don't write much code. $40 a month. Incredible.

I built 3 functional web apps in 4min… on my phone! Replit ⠕ Agent don’t just review and write code, their AI agents plan the functions, create development environment, install dependencies, write the code, configure databases and deploy. Is this the beginning of the end of paying for software? What’d you create?

Dario Amodei says Nobel-laureate-level AI (Superintelligence) by 2026–27 still looks surprisingly close - and the turbocharger is a feedback loop where AI writes code and accelerates AI research to build even better models. He thinks full end-to-end AI software engineering could be just 6–12 months away - meaning the pace might jump from “fast” to “holy shit.”

Software Engineering Expectations for 2026 - The majority of your code should be written by AI now - Cursor/Codex/Claude Code/Gemini/etc - You should try all the tooling and switch between them, as each one gets an edge over the others depending on the release cycle. - You should be using AI to check the code that is written by AI - Have AI write tests - Have AI read logs - Have AI navigate your browser - I don't do this every time because sometimes it's simple enough to check it myself - You should still skim code changes - This can be a lighter skim on internal tools and a heavier read through on customer facing code - Use AI to help you define specs

“Software engineering is changing, and by the end of 2025, it's going to look fundamentally different.” OpenAI co-founder Greg Brockman says Codex is a remote software agent that runs in parallel in your repo, and writes code like a teammate. The new model is optimized from o3 to produce mergeable, real-world code.

In software engineering we have so crossed the line. This is from Claude Code creator Boris Cherny (Boris Cherny ) "I don't write code; I prompt Claude. Actually, nowadays, what I'm mostly doing is having one Claude prompt other Claudes. So I don't even talk to Claude directly. I have a Claude that's talking to my other Claudes. I think in engineering, we've seen an explosion in the amount of leverage that a single person has. It's about how big of a business one person can build and how many products one person can support." ---- From "Alex Kantrowitz" (Alex Kantrowitz) YouTube channel, (full video link in comment)

This is what the future of software development will look like. AI writes 80% of the code. Human devs finish the last 20%. The next wave of models will begin to unlock the potential of these tools. Massive AI codegen wave incoming.

Creator and head of Claude Code, Anthropic: "I don't prompt Claude anymore. I have loops running that prompt Claude and decide what to do. My job is to write loops." He hasn't hand-written a line of code since November. 100% is Claude Code now. Still ships 10 to 30 pull requests a day. He breaks down his actual workflow in the 1h28m podcast. Loops writing 100% of the code. Engineer leveling up, or automated out?

Anthropic CEO: “ I have engineers within anthropic who don’t write any code, they just let Claude write the code and they edit it and look it over” “At anthropic writing code means designing the next version of Claude it self, so we essentially have Claude designing the next version of Claude itself, not completely but most of it”. In the last 52 days, the Claude team dropped 50+ major feature launches. This is literally INSANE.
