Engineers Are Highly Opinionated

Why do you think we C++ or Rust was borned? No, let think about why do we go from punched card to Assembly to C to C++ to Rust? It's probably some or many guys feel that the current approach is inefficent and inadequate. Yeah, they're probably opinionated.

New web frameworks are introduced every month. There're like hundred of different cloud database providers even though we just have SQL DB with MySQL, PostgreSQL, and MySQL and NoSQL. For slightly large-scaled technical problems, we have dozen of different approaches to solve them. For slightly large-scaled technical problems, we have dozen of different approaches to tackle them. These all come down to software engineers and architects believe in their own unique and 'optimize' approach. It is also hard to measure whether a approach is better or not since most of the time the end results is basically identical. Whether you use Next.JS or Astro, though they have some innated differences in performance, your customers will probably never know that they are using a highly optimized Astro's island architecture with built-in react compiler (those are the main topics I found on daily.dev and I have no idea what I'm talking about).

Since it's kinda hard to know weight different software approaches against each other, they just keep existing unless some drastic performace different or breaking bugs occur. For that reason, software engineer can keep being opinionated about their tech stacks and frameworks since having a concrete answer to a software debate is futile. I mean even artist don't have that much opinions about their favorite art eras and styles.
