I think there is a problem in that a number of current developers never went through the era where SQL (whatever DB you want) was the only choice. Specialized DBs came about - NoSQL, Graph, etc. Developers not trained in or experienced with the basics go with what they deem shiny and interesting. As experience grows, one realizes hey, maybe something like Postgres makes sense. It's better to go with "what works" and then optimize. Sadly, too many developers don't have the breadth of experience to know the tradeoffs.
