The only place I’ve seen technical debt and organic complexity come from in real life is from over-engineering (Einsteins over-engineer the code, and Elvises bring in too many dependencies) and, more importantly, from changing requirements (customers & PMs & management). The changing requirements is the bigger culprit most of the time, and that doesn’t reflect directly on programmers or programmer personalities. I’ve never seen efficiency arguments make the code unwieldy. If anything, the problem is that real life Morts sometimes under-engineer, and it takes some of the other types to build up a bit. I’ve seen over-engineering far more often than under-engineering. Anyway, Mort only means short-term efficiency if you make assumptions. It didn’t in the top comment, and it doesn’t have to, you can just as easily assume efficiency is long term and includes efficiency of maintainable code and efficiency of business processes. If you care about the business outcome, why would you jump to the conclusion that it’s short term thinking?
