Yes, I hate the mentality that unit tests are the holy grail. I work in data science. A lot of data scientists are very mediocre programmers. The solution was for software engineers to assert that data scientists at our org should work more like them. Test coverage is pushed as a critical metric. But it's really a terrible fit for what we're doing. Data science QA needs to track the state of the data at different steps in the pipeline. Unit tests, imo, are better suited to uses cases that deal with user input where you can concretely cover a good spectrum of expected states. Not all unit tests are bad of course, but many in my context, imo, are unhelpful.
