Complexity arrives as drift

Complexity rarely shows up as one big architectural mistake.
It shows up as small, reasonable additions. One integration. One exception. One "we'll clean it up later." One flag that never leaves.
Each step is defensible. The system gets harder to reason about anyway.
That's complexity accumulation: not one failure, but drift.
Eventually three people estimate a change because nobody holds the full picture. Performance and reliability get political because nobody wants to touch the fragile middle.
The fix isn't always a rewrite.
Often it's visibility, boundaries, and removing what no longer pays for itself.
Systems don't become complex overnight.
They become complex because removal is harder than addition — and addition is always urgent.
