> I don't think Vue would scale well
It kinda bothers me when people say X won't scale (implying that React is somehow special in this regard).
For one thing, we're not talking about things like database throughput where you can actually have scalability bottlenecks.
If we want to talk about scaling maintainability, React is definitely not much of a poster child either, compared to other solutions I've used over the years. We got a new context API only recently to deal with concerns Angular had already accounted for years ago, and things like the Enzyme adapter state of the world is pretty terrible - and don't even get me started on React Router migrations :)
IMHO, one major thing Vue did right that React didn't which has an impact on scaling maintainability is that Vue owns its most important peripherals (data management via vuex, styling via single file components, animations, etc). In my experience, the React model (also adopted by webpack and babel) is a real pain in the ass to support at scale as a web platform engineer, because many times you're at the mercy of some random dude with no connection to the core project and you end up having to settle with bizarre makeshift configurations, fork things or do other nasty things to get around random design direction changes.
