"What's worse than data silos? Data silos that invent their own query language." - Erik Bernhardsson
In his infamous and widely discussed blog post named ' I don't want to learn your garbage query language,' Erik Bernhardsson expressed what so many other Data Engineers and Analysts related with so strongly. Namely, that he "really [doesn't] like software that invents its own query language" and that he "just [wants his] SQL back."
The fairly short-yet-passionate rant summarized the almost universal experience that technologies that require their own language often produce a whole new different set of complexities.
