Here's what is buried a bit in the text:

Something like 95% of vinext is pure Vite. The routing, the module shims, the SSR pipeline, the RSC integration: none of it is Cloudflare-specific.

The real achievement is human-built Vite (and it is an amazing project).
Since Next.js's API surface and capabilities are known, this is actually quite a good use of AI: re-implement some functionality using a different framework/language/approach. They work rather well with that.

From TFA:
Vite is the build tool used by most of the front-end ecosystem outside of Next.js, powering frameworks like Astro, SvelteKit, Nuxt, and Remix
Are you saying those frameworks aren't impressive because they are also powered by Vite?
Also from TFA: A project like this would normally take a team of engineers months, if not years. Several teams at various companies have attempted it, and the scope is just enormous. We tried once at Cloudflare! Two routers, 33+ module shims, server rendering pipelines, RSC streaming, file-system routing, middleware, caching, static export. There's a reason nobody has pulled it off.
That's the most important result of this experiment. They achieved something that they'd wanted to do but couldn't pull it off. Do you think they are lying?
