Never in the history of software has that line done anything but gone up. Software naturally gets more complex as it grows to handle new features, new edge cases, more users, more backwards compatibility, etc.

This line going up is inevitable and natural. The slope needs to be managed obviously. But the only way this line stays flat is if your company is failing.

Most software has short periods when it goes down. And then go up again.

I think the correct framing is that it should go up only with the logarithm of the code's age or size. If it's going any faster, you have a problem.
