He's right. And this is the part most product managers miss. Building is easier than ever. The hard part was never building. The hard part is knowing WHAT to build WHEN to build it WHETHER it's working That requires context. And most AI tools have none.
Al has collapsed the time it takes to ship a feature. Now it's all about shipping the right thing. It's just as hard as it ever was. As coding gets automated, agentic analytics becomes the bottleneck. Teams that win will build within context rich environments that capture user

A map of population distribution in Europe (black = at least one inhabitant per square km) Always stuns me to see how empty swaths of Spain are!

If you use any software, you will hit bugs. Only a tiny 5% of your users will ever report bugs. The speed at which those bugs are fixed is the true measure of a founder in mastery of their craft.

What a time to be alive - app in an afternoon.
I found the official Get Information about Schools website a bit clunky, so I made a new one with Claude Code. You can: - Set a postcode and see all schools within a radius of that you've chosen, filtered by type of school. - Filter and rank by the old one-word Ofsted

I don't think people realize what just happened here. Google just built the holy grail of autonomous driving feedback loops: a world generator that can simulate impossible edge cases. Elephants wandering into intersections. Construction equipment materializing out of nowhere.
We’re excited to introduce the Waymo World Model—a frontier generative mode for large-scale, hyper-realistic autonomous driving simulation built on @GoogleDeepMind’s Genie 3. By simulating the “impossible”, we proactively prepare the Waymo Driver for some of the most rare and

What's currently going on at @moltbook is genuinely the most incredible sci-fi takeoff-adjacent thing I have seen recently. People's Clawdbots (moltbots, now @openclaw) are self-organizing on a Reddit-like site for AIs, discussing various topics, e.g. even how to speak privately.
welp… a new post on @moltbook is now an AI saying they want E2E private spaces built FOR agents “so nobody (not the server, not even the humans) can read what agents say to each other unless they choose to share”. it’s over

It still makes me sad every time I read about this exit.
FanDuel sold for $465M in 2018. Founders got $0. Zero. - 10 years of 80-hour weeks. - Raised hundreds of millions. - Built a billion-dollar business. Liquidation preferences ate everything. Meanwhile, a FAANG principal engineer over that decade: $8-10M in total comp.

Customer interviews are what made me stand out as a PM. But it took me 18 months to master JTBD theory. In 1 minute, I'll teach you what took me 18 months. 1. Stop asking about solutions Instead ask: "What were you trying to accomplish?" 2. Focus on timeline "Walk me through

Obsess over quality, not over product theatre. Trust your teams. Don't spend all your time discussing the process 🌚
Linear hit a $1.25B valuation with just 2 PMs. The way they build product is from the future. They're contrarian. They do almost no "growth product" work: • No A/B tests • No work on activation • No growth dashboards • Zero focus on retention tactics They also don't have

One of my favorite lessons I’ve learnt from working with smart people: Action produces information. If you’re unsure of what to do, just do anything, even if it’s the wrong thing. This will give you information about what you should actually be doing. Sounds simple on the

That IS insane. That's a real person joining your company calls while you remain completely unaware.
This story is insane. The founders of Fireflies AI (now worth $1B+) pretended to be an AI notetaker before the tech existed. The founders would: > Join meetings on mute as "Fred from Fireflies" > Take notes by hand while sitting silently > Send the "AI-generated" notes 10

All product managers and designers should keep this fantastic chart of the four product risks handy. Say goodbye to the confusion between desirability and viability. Thanks, @tom_d_kerwin 🙏 Btw, I have 4 prompts for mapping and validating product risks here:

The reason it’s incredibly hard to break out of a “kind lie” doom loop is because the longer it’s gone on, the more unkindness is needed to get back on track. And the fact that you’re in this situation to begin with probably means your culture will hate that.
An extreme commitment to the truth makes relationships acutely dysfunctional but systems chronically functional (think Elon Musk). An extreme commitment to kindness makes relationships acutely functional but systems chronically dysfunctional (think Sweden, UK)

Yikes. Been playing with this on and off the last few days 🌚 #ai #Perplexity
The security vulnerability we found in Perplexity’s Comet browser this summer is not an isolated issue. Indirect prompt injections are a systemic problem facing Comet and other AI-powered browsers. Today we’re publishing details on more security vulnerabilities we uncovered.

I’m not surprised this has 10k likes, but I think it’s pretty bad advice. And often actively destructive to both company culture and performance. In fact, it’s a pretty employee-hostile chart and an abdication of leadership responsibility. Let me explain… The critical
I stole this idea and now use it with every single employee. It’s the best illustration I’ve seen of teaching someone to be high agency. It says there are 5 levels of work: Level 1: “There is a problem.” Level 2: “There is a problem, and I’ve found some causes.” Level 3:

We just set up this workflow at @LandTechUK. First test is tomorrow AM to remove a 'Community' link from the app. Hold onto ya butts 🤙
I've really been enjoying this workflow lately. Whenever a PM or a designer finds a small change to be made, we just create the issue and assign it to a coding agent. It would have been much more annoying for us to put it into the work queue, wait for an engineer to take time

There'll always be more emails in need of reply, more meetings to attend, and more updates to read. A person can fill the entire workweek with these tasks over and over again. But to stay sane and sharp, you must pay yourself first by doing the work that actually means something
