Welll, yes I think the case is proven for MongoDB and the like, but is the author beating up on the easy ones? Some examples that come to mind: - Postgres. MySQL is great but was eventually obtained by Oracle with a questionable open source future. I think they both originated long ago and evolved in parallel. I wish author would weigh in on which should not have been developed. - Julia is a new dynamic language that intends to perform with speeds like C. But shouldn't we stick with python because that is the current standard? Wait though, the author says Python is just the same as javascript, ruby, and PHP. PHP was first, so I guess I should be doing my data science in PHP? I think languages and ecosystems are more analagous to companies/enterprises. They evolve, arise, and die out. Some succeed.
