Don’t forget developmental complexity. The real limited resource is developer brain power which is the primary (and legit) reason for most failures to optimize algorithms.

Sometimes the most optimized solution requires a developer with enormous working memory, who can write code nobody else on the team can follow.

I worked on an app as a subcontractor once and this guy had functions generating functions to generate functions. It worked, and it was parsimonious in a way. Like he was optimizing for the bundle size and it was pretty impressive, but I simply couldn’t get anything done because the way it was structured required me to hold like 12 chunks of info in my 7-chunk working memory.

I eventually got some progress but only after I had transferred a significant amount of the code into my long-term memory. (As an autistic my working memory was shit growing up so I learned to use my long term procedural memory as a stand-in for short term memory. Problem is it’s a brittle strategy, doesn’t respond to changes well, and is highly sensitive to what kinds of patterns are used).
