I almost entirely agree with you. When I first started working I was spending about 95% of my time debugging code that I inherited. However, as I wrote more unit tests and cleaned up the code that has dropped to less than 5% of the time and most of the time is spent on actual development. Features are delivered faster and the bug rate has dropped to almost nothing. The ones area I don't entirely agree with is when doing software based on math modeling it can often be worth it to take some additional time to go over the math design and check all the assumptions, stability, ways of solving it, alternative approaches, etc. I have run into too many cases where someone just started implementing a model with some pretty bad consequences. I like iterative coding and delivery but I really want to at least try and make sure the math we are going to implement is the right math to solve the problem we really have.
