It’s about what is being optimized. Evolution optimizes for cost:reproduction-benefit of path-dependent small changes, so you get a lot of reuse and deeply interdependent systems. Humans tend to optimize for ability to cheaply build and support.
So “easiest to design”, but really “easiest to manufacture from cheap/standard subassemblies”. Note that human-built systems have a lower level of path-dependency. Evolution requires that every small change be a viable improvement in itself. Human design can throw away as much of history as it likes, as long as it’s willing to spend the effort.
