The other problem is that if you didn't actually write the first 90% then the second 90% becomes 2x harder since you have to figure out wtf is actually going on.
Right— that’s bitten me ‘whipping up’ prototypes. My assumption about the way the LLM would handle done minutiae ends up being wrong and finding out why something isn’t working ends up taking more time than doing it right the first time by hand. The worst part about that is you can’t even factor it in to your already inaccurate work time estimates because it could strike anywhere — including things you’d never mess up yourself.
