I don't see it that way -- I feel like NoSQL's rise was more or less coincident with the adoption of Rails, Django, and Node over Java. The surge in interest in new static languages has mirrored the resurgence of Postgres, right around version 9.4 (and JSONB).

Could be. I haven't thought too deeply about what happened when.

I think they're both responses to the same challenges: distributed web enabled applications.

On the server front that means ever increasing complexity with decoupled microservices and latency issues that play nicely with the classic approaches to those domains (static typing, functional programming).

On the data front sites like HN, Reddit, or Facebook need scability more than consistency, and have oodles of 'uninteresting' data that jives nicely with a schemaless document store.

I've noticed that, too. There's an interesting ping-pong effect where a fair number people have flipped from strong typing at the database layer & dynamic typing at the view layer to the reverse — it seems like someone could write an interesting group psychology paper about how that cycle has repeated over the years.

I don't think I'm a Luddite but I always had the feeling I just had to sit out the noSQL / JS everywhere storm.
