We need a new 80/20 rule. I propose a 90/0. You get 90% done quickly and the other 0% over the next few years .
> The first 90% is easy/fast/cheap, it's the second 90% that's hard/slow/expensive
Since most of the generative approaches treat code as disposable, then the second (and subsequent) 90% approaches just throw it away and start over. It's like all the awesome parts about a rewrite, with all the awesome parts about "it was rewritten because no one understood it"
