My experience is that Agentic Coding can legitimately get you mostly-working software. You do, however, still need to spend a few days groking, validating, and usually nudging/whacking it to conform to the shape you intended vs what the agent inferred.

It is pretty magical to go from brainstorming an idea in the evening, having ChatGPT Pro spit out a long list of beads to implement it, leaving it running over night in a totally empty repo and waking up to a mostly-implemented project.

It's magical until you start going through the code carefully, line by line, and find yourself typing at the agent: YOU DID WHAT NOW? Then, when you read a few more lines and realise that neither AI nor human will be able to debug the codebase once ten more features are added you find yourself typing: REVERT. EVERYTHING.
