I don't think so. I just think right now Vercel is very good at marketing and lots of new programmers and hopping on the NextJS train. There are tons of materials out there for building apps quickly and it's very appealing for newer developers, particularly the bits where getting a site deployed is as easy as running a couple commands w/ the Vercel CLI.

For larger applications, I don't see meta-frameworks eating up a significant chunk of the world since they're very expensive to run in certain situations. Especially so if you use the default deployment options and rely entirely on serverless functions for your infrastructure or a database-as-a-service like Firebase/Supabase. I think it's inevitable that people will carve bits and pieces off of their meta-frameworks into different types of applications as they scale, just in the same way that people carve up their Rails applications of yore.

I generally think that the meta-framework obsession will also help propel backend SSR + HTMX, since thinking in server-side components is easier to translate to traditional backend SSR than SPA -> backend.
