Every's eight-level AI adoption map is useful because it measures delegation, trust, context, and verification, not personal intelligence. This version expands the ladder and pairs it with a self-assessment that checks how people actually work with AI.

Cerebras is interesting beyond its IPO because near-1,000-token-per-second inference changes the shape of the work: draft, check, repair, compare, and return before the human loses the thread.

The useful question is how much AI capability would still remain if the proprietary frontier disappeared tomorrow.

The common claim is that AI cannot replace your job. That may be true. But jobs are bundles of functions, and the better question is which functions are already moving closer to reliable AI handoff.

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 genuine multi-agent runtime across different harnesses: paired review loops, handoffs, shared threads, and open protocols such as A2A.

As of March 24, 2026, mobile AI coding is splitting around where the work runs: a phone steering your own machine, or a phone 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.

Agent Memory Architecture

A public interactive explainer showing how modern agent memory systems layer extraction, versioning, multimodal recall, and source grounding around stateless models.

View project

This interactive explainer is the clearest companion page to my writing on agent memory.

Use it if you want a faster mental model of how modern AI systems simulate memory without making the base model itself stateful. The important shift is architectural: extraction, recall, versioning, temporal ordering, and source grounding are being built around the model rather than magically inside it.

What this page covers

The page walks through the main memory layers that matter in real agent systems:

raw conversation or document capture
memory extraction into smaller reusable units
retrieval across text and multimodal material
update logic for facts that change over time
source grounding when the agent needs the original evidence again

How to use it

Start with the high-level flow first, then use the deeper views to compare retrieval, updates, and memory policy. The goal is not just to memorise terms. It is to understand why "memory" in agents increasingly behaves like state management rather than simple search.
