I have a background in both SQL adn Oracle and I must say the Oracle DBA's have felt this pain much more over the years. Their setup was far more labor intensive leaving less time for the DBA to focus on providing service to customers.

"So perhaps the role of the DBA isn’t necessarily dead, it’s just moved to its new home at the datastore-as-a-service provider. "

We have been working under that model for years, long before visualization. Developers are free to build objects in development and new projects can start up in minutes on existing systems. Do they make mistakes? Absolutely, and then they call an experienced DBA for assistance.
