It's moving somewhere from "not quite there yet" to "substantial, qualitative improvement" as we speak. I'm following what happens in that space with React/Node based things like Next, and Redwood (soon v1.0), and others. The building blocks are there and the integrations get better and better.

The big win of those will be tighter frontend and development integrations that are just not as feasible with a different language stack (PHP/Laravel, Python/Django, Ruby/Rails).
