I explore 30 year old tech (Content negotiation in HTTP) and how we might use it on the web with LLMs.
If you have the ability to transform any content into any content we can get a web that is built to be personalised to every single person in their preferred medium.

LLMs and generative technology can change the way we think about creating and managing content. Specifically, we can apply *layout and functionality* to pages through prompts how CSS helped separate content from the style.

Whither CMS? I think the CMS industry is up for a massive change with the introduction of LLMs. Historically CMSs tend to be used at the long-tail of the web where there is little traffic, it's also the space where people might be more willing to use new tools.

I've been thinking about the effects of tokens and how it impacts direct web development. Feels like there is a change in that we are now back to paying for our IDEs (even if it's indirectly).

📰 Dead Framework Theory
💬 React's reign might be over as LLMs could liberate us from its compilation woes. Mixed feelings on whether this is great or dreadful. 🤷♂️

I had fun last night. I got a Chrome extension to talk MCP via the Omnibox. It can even render and host OpenAI's Apps SDK runtime "Skybridge" - I have a small shim that attempts to polyfill the API.

Agree. I think LLM tools likely have to output React by default today. However LLMs need to work with any framework in brownfield, so enabling other outputs as an option becomes somewhat easy to implement - enterprise user might choose due to corporate policies and hobbyists for any reason.

Last but not least, the incumbent always had a strong advantage (nobody gets fired for buying IBM) - which didn't in the past stop innovation from happening or players to come up. Our belief in the team is that innovation will continue until UIs are a solved problem, which we think is far from true!

at least when the developers are interested in it. Also new features/API might matter if they're better performing then generated patterns, and even more ergonomic syntax might be useful to humans AND LLMs in all but greenfield use cases (if only to save tokens on maintenance).

I've been so annoyed by AI tools and CSS that I made a CSS MCP that:
* consults with MDN for docs
* reports browser compat
* uses project Wallace to analyze your CSS

Also made claude code agent for css but still perfecting it.

Little @codepen.io demo: single `img` squircles + grainy inset shadow codepen.io/thebabydino/...
(for `img`, the actual image is content & gets painted on top of shadows; the earlier workaround has been a sibling/ parent's pseudo used as a "cover" that gets the shadow; none of it here 😼)
