LLMs can absolutely bust out some corporate docs super crazy fast too... probably a reasonable thing to re-evaluate the value though
I had a working and complete version of Apple MapKit JS rendering a map for an address (along with the server side token generation), and last night I told it I wanted to switch to Google Maps for "reasons".
It nailed it on the first try, and even gave me quick steps for creating the API keys in Google Dev Console (which is always _super_ fun to navigate).
As Simon has said elsewhere in these comments, it's all about the context you give it (a working example in a slightly different paradigm really couldn't be any better).
I have a project with a bunch of tests already, then I pick a test file and write `public Task Test` and wait a few seconds, in most cases it writes down a pretty sane basis for a test - and in a few cases it figured out an edge case I missed.
