Not only that, "data scientist" is just a marketing gimmick for consultants. It's a standard set of skills that anyone trained in science or engineering has. It's ok to use it in front of pointy headed bosses but in front of nerds it's slightly dishonest.
The science in data science involves testing hypotheses, like anyone following the scientific method would do. It's mandatory for validating ML models.
OK, but that doesn't mean "if you're an engineer or scientist, you don't see the science in data science" is a true statement. It's categorically false.
