I read the comments and see there are two types of engineers - conservatives and liberals, those who work for big corporations, draw UML diagrams with factories, bridges and facades and throwing arguments that because of some regulations or privacy policies your architecture can change and you need to be prepared for it. Those guys are right.

More liberal engineers are saying that keeping code simple is the key and to keep it simple you need to be smart and creative. Those guys are right as well.

Now back to reality, the conservative developers will always work on the code that was written by liberal developers because the latter deliver sh*t in time that works and carry the business on their shoulders, where the first makes it work in another scale.

Conclusion - there are different types of engineers and our responsibility is to accept that humans are not machines and somebody likes to CREATE vision and value, others like to manage huge system that are complex.
