Most software engineers I know love to build software for the sake of itself. They are not all that interested in the business. Most businesses for which software is being produced is not personally relatable or interesting to most software engineers.

To keep engineers motivated, the work has to have sufficient amount technical accomplishments and not just churning out business features.

Luckily, due to continuous growth in market and scale of users, and improvements in hardware, there is opportunity for serious amount of technical work in any project.

Also, faster time to market is of real business value. Compromises are done in ideal perfect designs to meet timelines (or resource constraints) – hence, tech debt occurs and it is real and just as useful as financial debt to help scale a business in a competing marketplace.

And speculative/iterative market feedback based development is also real. All these things add up to one thing – things that were right for yesterday isn't right for tomorrow.

So we have to rewrite or refactor software continuously. And that's perfectly normal. It is actually one of the biggest strengths of software based solutions – that we can change things live - while it is already in use - change the engines of the rocket while it is flying - so to speak. We have to embrace this and leverage it disruptively.

Those who pine for perfect software are denying realities of the larger real-world.
