I've worked on nearly a dozen Data Lakes. I have never seen nor heard of anyone who said that Data Lakes meant you could avoid ETL. If anything it has necessitated more of it as users expect to join these disparate data sets.

There is after all a reason that the role Data Engineer became popular just as Data Lakes become popular.
