TL;DR: Run a small team, not a tech behemoth? Embrace the monolith and make it majestic. You Deserve It!
My favorite is at the end:
The Majestic Monolith doesn’t pretend to provide a failsafe architectural road to glory. That’s a fool’s errand. Many programmers suffering under many oppressive influences will turn any architecture made with any tool into a big pile of mud.
IOW the Rails Way will get you started down the road, but eventually you’ll have to choose the right forks in the road. As is the way with any technology, no matter how much it turns its nose up at Rails :p.
