Anyway, our junior engineer edgelord friend here did not read every line of SQLite, MySQL or Postgres before choosing a backing store. I’ll even bet you a dollar they just gave AWS a CC number while saying “actually obviously scale”.
My experience - and this may not be yours but it’s definitely mine - is that the way people who say stuff like this actually make technical decisions is by puffing out their chests like a pigeon and repeating some shit they saw in a hackernews comment last week.
