EstiShay filed a bug report that’s concerning.

Last week at Microsoft Build, Jessie Lorenz, Carie Fisher, and I gave a short talk on a question every AI-enabled product team should be asking: can your AI pass the accessibility test?

At Microsoft Build 2026, Jessie Lorenz, Carie Fisher, and I looked at what happens when AI accelerates software development without accessibility built into the workflow.

At Ability Summit 2026, I moderated a panel on a question that feels more urgent by the day: how do we prevent accessibility defects before they get baked into AI-assisted workflows and shipped at scale?

Sometimes the simplest form pattern is the one you repeat ad infinitum: “Type it once, then type it again.”

This is a pointed reminder that AI trained on an inaccessible web will reproduce that inaccessibility at scale — unless we intervene thoughtfully and intentionally.

This post is a detailed and useful look at GitHub’s accessibility agent experiment.

As AI accelerates how software and content are created, accessibility risks emerge earlier and propagate faster than traditional testing and remediation can handle.

Cory Doctorow offers a characteristically sharp critique of the AI bubble, but what I found most useful here is his framing of how these systems are actually meant to be deployed: not to empower workers, but to turn them into “reverse centaurs.”

Eric Bailey walks through a clever pattern for getting the feel of nested interactive controls without sacrifice the platform’s semantics to get there.

This is a compelling illustration of what becomes possible when a design system is structured well enough to be usable by both people and machines.

Adobe has produced a tremendously useful resource for anyone working with Shadow DOM and trying to understand where modern CSS features actually stand in practice, not just in theory.

An important and sharply argued framing of AI-generated accessibility failures as a civil-rights problem, not just a quality-control issue.

It’s just a radio button.

The framing Anna Cook uses for her talk is an important one: accessibility isn’t something generative interfaces will magically solve; it’s the groundwork we need in order to make those systems trustworthy at all.

I’m very excited by focusgroup: a declarative way to handle a bunch of keyboard-navigation patterns that currently require a lot of brittle JavaScript.

The latest WebAIM Million is a sobering reminder that, at scale, the web is getting more complex faster than it is getting more accessible.

This is a fascinating look at how MDN rebuilt its frontend around server-rendered HTML, web components, and a clear understanding of where interactivity actually belongs (and how to deliver it).

This is a sobering but necessary reminder that the open web’s current crisis is not theoretical; it’s already playing out across publishing, open source, standards, and shared infrastructure.

This is a lovely little utility from Chris Coyier that turns CSS custom properties into a live control panel.
