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.
30 years ago? I talked to an project manager that designed and built factories. He said there were three kinds of engineers and techs he hired. Design, Construction/Shakedown and Maintenance. Design requires being creative and methodical. Construction and Shakedown requires the ability to gleefully beat chaos into submission. And Maintenance is the methodical following of rules and procedures. He hired three different groups for these tasks because they would go insane or be overwhelmed if they were doing the wrong job for their temperament and skills.
I like the interpretation of 'conservative'/'liberal' as applied to engineering practices which Steve Yegge wrote (in a lost Google+ post): "acceptability of breaking code in production".
'Conservative' developers really wants to 'conserve' what's there. I feel that description suits both the 'draw UML diagrams with enterprise patterns' as well as 'loves dependent types' kinds of people.
In this sense a liberal 'keep code simple' is more about things like "You Ain't Gonna Need It", and focussing on writing what code is needed now. (Since it doesn't matter if it needs to be broken later as requirements change).
