great interview
Lenny Rachitsky@lennysan

"Using coding agents well is taking every inch of my 25 years of experience as a software engineer." Simon Willison (@simonw) is one of the most prolific independent software engineers and most trusted voices on how AI is changing the craft of building software. He co-created Django, coined the term "prompt injection," and popularized the terms "agentic engineering" and "AI slop." In our in-depth conversation, we discuss: 🔸 Why November 2025 was an inflection point 🔸 The "dark factory" pattern 🔸 Why mid-career engineers (not juniors) are the most at risk right now 🔸 Three agentic engineering patterns he uses daily: red/green TDD, thin templates, hoarding 🔸 Why he writes 95% of his code from his phone while walking the dog 🔸 Why he thinks we're headed for an AI Challenger disaster 🔸 How a pelican riding a bicycle became the unofficial benchmark for AI model quality Listen now 👇 youtu.be/wc8FBhQtdsA

@BrandonGleklen i like your take Brandon, I think overall vibe diligence is a great thing if used well, it should push you to learn faster, digest 100% of a data room and remove the diligence “cold start problem” … but end of day you should always land in the main 2-3 questions that matter.

Google Research! Quantum getting much closer to reality. Willow chip ran a “Quantum Echoes” algorithm ~13,000× faster than the best supercomputer: real, verifiable quantum advantage, not just lab hype. New research says a future quantum box with <500k qubits could crack today’s Bitcoin/Ethereum-style crypto in minutes… ~20× fewer qubits than people thought, and Google is now targeting 2029 to move its own infrastructure to post‑quantum encryption.

I think this clearly shows the direction of both OpenAI and Anthropic, consumer vs enterprise

On "kingmaking": No firm has articulated the logic of kingmaking more explicitly than Andreessen Horowitz, which in January 2026 announced $15 billion in fresh funds — more than the next two largest VC raises of 2025 combined. As Packy McCormick documented in a recent 16,000-word anatomy of the firm, a16z's culture doc holds that there is "no bigger investing sin" than backing the second-best company in a category. Once a16z identifies its candidate king, the classic move is to give it more money than it thought it needed. When Ben Horowitz met the Databricks founders and they asked for $200,000, he refused — and wrote a check for $10 million instead. As a16z partner Alex Danco put it, the firm's purpose is to function as a "legitimacy bank": conferring the credibility that lets a nascent startup sell to Fortune 500 buyers and hire senior talent it has no business competing for. That legitimacy now extends to a full in-house media operation — a "New Media" team led by Erik Torenberg that embeds with portfolio companies during product launches, runs timeline takeovers, and deploys storytellers to shape narratives in real time. When Flock Safety faced a PR crisis, a16z's team joined its Slack channels; when World Labs launched its Marble product, a16z's crew shot the announcement on a 3D LED volume stage. The capital is the headline. The machinery around it is the moat. vector.news/p/does-kingmak…

This debate about foundation models versus vertical solutions reminds me of the early internet. Back then, everyone thought they could just “go online” and sell products themselves.. but the reality was far more complex. To actually sell online you need: - A platform to upload products with correct descriptions - A payment processor - Automated invoicing - Packing and shipping with SLA-compliant visibility - Delivery notifications - Handling refunds, returns, and vendor coordination - Updating inventory and accounting Services firms choose specialized solutions over Claude because companies don’t just want tools, they want software that codifies workflows, ensuring predictable outcomes through autonomous systems. Agents can enhance efficiency, but they don’t replace the need for structured processes. True leverage comes from redesigning your company around these workflows.

Huge misunderstanding by everyone why companies buy software. Companies don’t want every employee doing every workflow from scratch on their own for every use case. At some point what you’re outsourcing is the ability to not have to think about the business process, and instead let the software provider think about it. Agents don’t change that, and probably if anything exhibit that dynamic even more.

Financial statement re-shuffle across the P&L, balance sheet, and cash flow.. another example: Oracle Corporation is reportedly cutting 20–30K employees (~18%) to unlock ~$10B in annual cash flow, redirecting opex savings into debt-funded AI data center expansion.

Why a16z Should Back Every Single European Founder That Moves to the US: "We should back every single European founder who moves to the us, like we should just reflexively say yes. That's a combination of two things. 1. The raw level of talent that the great education system provides. 2. The move to the US indicates a willingness to seek risk and a greater level of achievement." @pmarca Love to hear your thoughts on this @t_blom @immad @dessaigne @Bandrew @joshbuckley @collinmathilde @maccaw @taavet

This is for everyone who has a dream that simply seems out of reach. 11 years ago I started 20VC as an 18 year old in a bedroom in London. I didn’t know a single VC and had no money. I wrote down the names of three legends of the venture world. I have had two on the show previously and today I complete the list that 18 year old boy made. This was 11 years, 3,000 shows, 3,750 hours, in the making. Never give up, never doubt yourself, stay focused, row your own race. It will come through. Welcoming Marc Andreesen to 20VC today.

we all need to start moving to the right, re-thinking/engineering how work happens
Wade Foster@wadefoster

Today we released our new AI Fluency Rubric. We use it for every hire, focusing on what they’ve actually built. Last May we open-sourced V1. Hundreds of companies used it to screen candidates and develop teams. It worked. But the floor moved fast. An updated look at the 3 levels of AI fluency at @Zapier: 1. Capable: "I use AI to operate at a meaningfully higher level." 2. Adoptive: "I orchestrate AI and build systems that elevate how I work." 3. Transformative: "I re-engineer how work happens." We evaluate theses across 4 dimensions: Mindset, Strategy, Building, and Accountability. We're sharing V2 publicly for the same reason we shared V1: every company needs a framework for this, and most don't have one yet. Don’t see your role?

Rumored next-gen models (like Anthropic’s Mythos) could be 5–6x more expensive but dramatically more powerful. If so, AI starts to behave like a Veblen good, where higher price = higher demand. It might make sense that higher intelligence is almost always more expensive?

@chrija @Redpoint @loganbartlett Yep, but then you’re signing up to build and maintain a full communications product, with a low-margin operation and fairly average technical capacity

@eliasmufa @Redpoint @loganbartlett Completely agree. But most businesses are not fast-growing tech startups trying to become a generational company. Most companies are low-margin businesses where saving costs matters more.

This is a great report on the state of software and AI by @Redpoint - thank you, @loganbartlett! Where I disagree is the build vs. buy slide: 1) I'm not sure if it takes ~12 engineers to build/maintain a Slack clone for 1 customer. As AI keeps getting better at not only code gen but all software engineering tasks I think you'll be able to do it with a smaller team. Doesn't mean you should spend engineering time on it because I expect... 2) ... there will be agencies who specialize in this kind of work (e.g. build a Slack clone and sell customized versions of it). 3) ... there will be lots of cheap, (more or less) good enough Slack clones 4) ... there will be AI-native startups that rethink the category. All of these factors, I think, will contribute to pricing pressure for Slack and other traditional SaaS companies ... which they will only be able to defend against if they get a share of the agentic revenue enabled by their products.
