This actually makes a lot of sense. I have a lot of friends employed as Data Scientist or Data Engineers who don't seem to be able to explain exactly what they do, or describe what "research" they are doing. From what I understand, it seems like they are designing pipelines that ingest data, run an off the shelf AI algorithm and display nice graphs. There is a lot of pipelines you can design for different kinds of data so I imagine they always have something to do.
