I don't think its an age think at all. I think that Tableau and other BI tools killed the bulk of rudimentary SQL work for thousands of developers. And good riddance. Business people need to be able to have as much access to the numbers as is feasible, and should have to wait in line to get them.
I think that the fast majority of movement away from relational databases is pure folly. With JSON columns and horizontal scaling, relational DBs can handle virtually every workload, and give devs wonderful things like joins, aggregates, window functions, views, foreign data wrappers, user defined functions and all of this other stuff the have to build themselves on top of their "easy" NoSQL DB. There are many, many good use cases for document DBs, where they win on latency and scale. I've just seen a lot of NoSQL by default designs, or NeverSQL attitude, and those end up being very expensive to actually develop and own.
