The article is a rehash of other sources and not particularly original, although it packages it in an easy to consume format. It does have, though, an important insight that I haven't seen talked about much: when you do some upfront optimization (e.g. for scalability), even if you end up needing it, most often your solution ends up not being fit for purpose. This is true for startups, but it also applies to software in general. By the time your product is scaling, it will probably have gone through quite a few changes, and it's likely that what you predicted would be scalability bottlenecks are off the mark. Not to mention how damn hard is to predict what issues a product you haven't yet built will face on the first place.
