Thoughts
I have a lot of respect for Serenity OS, but I think LadyBird is a fool’s endeavor. Kling tweeted that he’s been asking ChatGPT for help
with understanding CSS layout, so he’s no web expert, and moreover he’s not working at the level of detail of the spec. I have nothing against ChatGPT for basic programming questions, but you’re not going to end up with a spec compliant web browser without reading the spec.
I think Serenity works because you can move quickly and build something new and functional without worrying too much about compatibility or tech debt. But with the web, that tech debt is standardized and impossible to remove.
The equivalent to creating a new operating system is not creating a new browser. It’s creating a new web-level specification. Creating a new browser is like trying to create, from scratch, an operating system that can run modified binaries which have been compiled and statically linked for Linux.
