Nextjs is most likely going to be the new Ruby on Rails. javascript all the way down, static rendering, PWA, server side rendering...everything baked in.
This is a big backing for Next.
However rebranding to Vercel is bad.
That's the objective of Blitz.js [1]: build on top of Next.js for a rails-like experience, but made by an independent open-source community.
