Optimized translates to, for a single use case.
The more form you give something, the narrower its uses become. Which is why innovative sites must spend years hatching schemes to work within “optimized” wheels. It’s why Google and Amazon have both created their own databases and left SQL behind. Because SQL is optimized for a very specific use case.
Then you get into other problems, like http(s). It was optimized for one-time connections, because you connect to something, send a request, get it, then the connection closes. Which lead to the need for WebRTC – which is an entire mess of its own, trying to get around that restriction.
Optimized means a use-case became narrower and narrower over time. One of the most reinvented things in history, other than the mousetrap, is the wheel.
