The thing that I keep wondering about: If the coding part is 2-5x more productive for you, but the stuff around the coding doesn't change... at some point, it'll have to, right? The cost/benefit of a lot of practices (this article talks about code review, which is a big one) changes a lot if coding becomes significantly easier relative to other tasks.
Yes, absolutely. Code used to be more expensive to write, which meant that a lot of features weren't sensible to build - the incremental value they provided wasn't worth the implementation effort.
Now when I'm designing software there are all sorts of things where I'm much less likely to think "nah, that will take too long to type the code for".
