I think acerbity is warranted to some extent. We are data scientists. We get paid the big bucks because we have big brains and have the skills and training to use those big brains in order to reason about the work we are doing. Data science has become so easy and accessible nowadays that basically anyone who can write code can fit and use models. That's a great thing in general, but it means that those of us who do this for a living really should hold ourselves to higher standards. Even if you are thoroughly mediocre at your job (like me) and aren't smart enough to come up with something like Prophet on your own, you absolutely do need the ability to reason about the models that you use, and to evaluate their performance correctly.
