This. Specially if you work with Node.js. The JavaScript community is susceptible to ignoring all previous knowledge, experience, wisdom and tries to reinvent everything. I appreciate the energy, but it is often misguided. Understand the difference between merit and marketing bullshit (stack names that include Mongodb?). Understand context. If you are using Node.js in green field project, you are probably better off using Postgres. Understand Lindy effect. Sql isn't going away, but the vendor specific query language that you are spending time with and hoping will replace sql is probably going to.
