Software 2.0 relies on validation

If your code base doesn’t have verification & controls that are as good or better than your senior dev, you’ll get slop
A large pink slide fills most of the image, displayed in a bright glass-walled auditorium. A presenter stands beneath it on a red circular carpet, wearing a dark T-shirt and dark pants, holding a clicker. Slide title (top, in large red text): “The Problem: Most Codebases Lack Sufficient Verifiability” Subheading in smaller text: “Humans work around incomplete infrastructure. AI agents cannot.” The slide is divided into two rounded pink boxes: ⸻ Left box: “What Humans Can Handle” A bulleted list in red text: • 60% test coverage (“I’ll test manually”) • Outdated docs (“I’ll ask the team”) • No linters/formatters (“I’ll review it”) • Flaky builds (“I’ll retry”) • Complex setup (“I’ll help onboard”) • Missing observability (“Check logs”) • No security scanning (“We’ll catch it later”) • Inconsistent patterns (“I know the history”) ⸻ Right box: “What Breaks AI Agents” Bulleted list with each line marked by a red “X”: • No tests → can’t validate correctness • Outdated docs → makes wrong assumptions • No quality checks → generates bad code • Flaky builds → can’t verify changes • Complex setup → can’t reproduce environment • No observability → can’t debug failures • No security checks → introduces vulnerabilities • No standards → creates inconsistency ⸻ At the bottom in a wide pink bar: “Most organizations have partial infrastructure across the eight pillars. AI agents need systematic coverage to succeed.” Tall windows behind the stage reveal greenery and modern architecture outside.

Had been looking forward, but goodness, the FM26 UI is terrible. Cluttered, and key elements bafflingly buried.
At least make the tiles customisable so we can remove the duplicated junk.

The fallout from the fact that data science/classical machine learning & generative AI are both called "AI" has been remarkably broad & persistent

Policy addresses the wrong harms, companies have been confused about who should lead efforts, hiring is misguided, academic discussion is often muddled.

Superb starter for the season.

A big tour through some key storylines for Arsenal's upcoming season, including Zubimendi's impact on the midfield, Heinze’s influence in attack, summer business, tactics, analytics, and Arteta’s plan to "change the puzzle."

Also ran an "OPPO" report on us. Enjoy. ❤️

Recently I’ve been asked to talk at several AGMs/Boards on building AI orientated firms. Here I’ve tried to share my lessons learnt and reflect upon how what’s important has evolved.

Observations on the necessary talent, patterns-of-play, and compounding acumen required to build high performance teams. And it’s impact on active investment.

In hindsight, not sure precision is actually the right word.

Human cartography, you all know how I love a good map.
I wonder if/how this changes the rules of generalisation.

Good conversation also wins.

Data, sport, OODA loops, private equity, active co-sponsorship, machine learning, high performance teams, Arsenal, loops not lines.

Good habits win.
