Conflicts are the least of our worries, and yes llms can handle that well. I’m taking about the things you can’t easily handle, the complexity that slowly overwhelms a codebase with no easy way out except a rewrite.
And a rewrite of a non-trivial application, even with the AI goodness, is still a big proposition and full of all kinds of risk. If you have a trivial application, you probably don’t have much protecting you from someone else vibing up a competing replacement either.
