Honest question: Where do you deploy? What do you use for queues? Database? It's impossible to beat React for component libraries but, lemme tell you, I've struggled to be productive with Next when compared to Rails.
I don't know if I'd admit that publicly, without first reading about it and trying to understand why things like RoR and Python have huge, loyal user bases.
I'm sure they meant an actual statically typed language. I agree that dynamic languages are fun and productive ... until the codebase becomes big and complex, and then not knowing what shape any data is quickly becomes a nightmare to understand and debug.
