Ah, the classic "too many cooks" scenario but with programmers! The left shows a beautifully simple, straight railway track representing your solo coding journey—clean, predictable, and headed in one clear direction. Then management decides that "adding more programmers will speed things up," and suddenly your elegant project transforms into that chaotic railway junction on the right—a tangled mess of conflicting ideas, merge conflicts, and "but on MY machine it works perfectly."
It's the software development equivalent of trying to make a baby in one month by getting nine women pregnant. Some problems just don't scale linearly with headcount, and codebases are notoriously allergic to sudden influxes of new contributors who each bring their own "brilliant" ideas to the table.
