From the short-term, economic perspective, watching someone hammer away at something when "tried-and-true" solutions exist (with some 'creative' twists ofc) can even seem irrational and wasteful. One famous Modernist architect, Phillip Johnson, even quipped that,"Architecture is the art of how to waste space."
People who can't handle the waste in design probably would never shell out for proper R&D or scientific developments either. Hardly anyone gets it right on their first try, even in research.
It's funny because when creative endeavors finally pay off, they can pay off big and then they themselves become the "tried-and-true" trend that people follow.
In the end I think desensitizing yourself to the idea of erasing work is a good practice. I have projects full of code that has been commented out for over a month, simply because I'm afraid I'll have to go back and see it again... Recalling this story, I may just as well delete it and rewrite it if needed. Chances are the rewrite will be cleaner.
My purview in education is broad and the sentiment is always "what will go wrong" and never "what could go right." In higher education it's this mentality amplified.
You might say HN is my safe space.
For me, that says it all about the bias against creativity.
Creativity requires a tolerance for uncertainty and risk. Don't ask for creativity unless you are willing to accept that.
