This is what I've seen as well - in the past a large refactor for a codebase like that seemed nearly impossible. Now doing something like "add type hints" in python or "convert from js to ts" is possible in a few days instead of months to never. Another HUGE one is terraforming our entire stack. It's gone from nearly impossible to achievable with AI.
