I kinda get it. To massively simplify: Without AI, your choice is 8 days implementing, or 5 days planning/designing/refactoring and 5 days implementing. With AI, your choice is 5 days wrestling with the AI to implement, or 4 days planning/designing/refactoring and 1 day with the AI to implement. I made up those numbers but the general idea is that good practices have a lot more leverage with AI, since the make the implementation "free".
