Loophole is not interesting because it solves ethics. It is interesting because it treats moral principles like something you can draft, attack, patch, and escalate until the real conflicts in your values finally surface.

Attio, Linear, and PostHog are converging on the same product bet: one fixed dashboard cannot serve every user or every intent, so the SaaS homepage is shifting toward an agentic entry point. Chat is the router. Generative UI is what comes next.

The next real step for agents is not just more subagents inside one product. It is genuine multi-agent runtime across different harnesses, using paired review loops, handoffs, shared threads, and open protocols such as A2A.

As of March 24, 2026, the biggest divide in mobile AI coding is not provider branding. It is whether your phone is steering a session running on your own machine or watching cloud agents work somewhere else.

Claude Code autonomy is not one trick. It starts with permission friction and context hygiene, then moves through subagents and loop hooks, and becomes genuinely useful when the system can measure whether the last iteration actually improved the work.

The newest memory systems do not make language models inherently stateful. They build recall, updates, and temporal reasoning around the model instead. Gemini Embedding 2 is the first mass-scale vector embedding that is multimodal.

The most useful way to understand AI progress isn't by tracking model names. It's by tracking the operating model: from chatbots that only talk to systems that can plan, act, coordinate, and increasingly sit across software.

AI can speed up individual tasks, but that does not automatically create more free time. From personal experience, the saved capacity gets filled by more complex tasks and higher expectations.

I write, build, and teach around AI, learning, and digital work.

Focus Areas

The main things I work on here: AI, learning, and projects, plus how the site is organised.

This site keeps returning to three main areas: AI, learning, and projects.

Those themes show up across the main sections below.

Main Sections

Essays

This is where I write about AI models, tools, applications, and the broader shifts around them.

Resources

This is where I keep practical notes, prompt libraries, workflow pages, and other reusable material.

Browse resources

Projects

This is where I put experiments, prototypes, smaller builds, and tool pages.

Browse projects

This is the easiest way to keep up with new essays, notes, links, and project updates.

Core Focus Areas

AI

I track new tools, model behaviour, agents, workflows, and the way AI is moving from isolated chats toward more capable systems.

Learning

I care about how people learn AI well: not just how to use the tools, but how to think with them and judge them properly.

Projects

I like making things. Smaller builds and experiments are part of how I test ideas instead of leaving them at the level of opinion.

If you are not sure where to start, start with essays, then resources, then projects.
