alt Hacker NewsDays after the fake story about Cursor building a web browser from scratch with GPT-5.2 was debunked. Disbelief should be the default reaction to stories like this.

The outrageous part of this is nowhere in the blog post or the repository indicates it's vibe coded garbage (hopefully I didn't miss it?). You expect some level of bullshit in AI company's latest AI vibe coding announcements. This can be mistaken for a classical blog post.
Although the tell is obvious if you spent one second looking at https://github.com/nkuntz1934/matrix-workers. That misaligned ASCII diagram, damn.
Why is Cloudflare paying this guy again, just to vibe a bunch of garbage without even checking above the fold content in the README?
I get vibe coding a feature or news story or whatnot but how do you go about not even checking if the thing actually works, or fact checking the blog post?
it seems as if literally everyone associated with "AI" is a grifter, shill (sorry, "Independent Researcher"), temporarily embarrassed billionaire, or just a flat out scammer
I have yet to see a counter-example
It's clear that on Hacker News many people have made absurdly deep investments into this "technology." There's going to be a long period of pearl clutching we have to dig out of until we get back to the standard hacker ethic of not believing anything published by corporations.
They did build a browser; it may not be a very compliant or complete browser, or even a useful one, but neither was IE6!
Btw, after I wrote that initial article ("Cursor's latest "browser experiment" implied success without evidence"), I gave it my own try to write a browser from scratch with just one agent, using no 3rd party crates, only commonly available system libraries, and just made a Show HN about it: https://news.ycombinator.com/item?id=46779522
The end result: Me and one agent (codex) managed to build something more or less the same as Cursor's "hundreds of agents" running for weeks and producing millions of lines of code, in just 20K LOC (this includes X11, macOS and Windows support). Has --headless, --screenshot, handles scaling, link clicking and scrolling, and can render basic websites mostly fine (like HN) and most others not so fine. Also included CI builds and automatic releases because why not.
The repository itself is here and should run out of the box on most modern OSes, downloads can be found at the Releases page: https://github.com/embedding-shapes/one-agent-one-browser
