alt Hacker News Why hasn't it gone away already? ChatGPT at least has been around for over 3 years.
ChatGPT didn't have your whole codebase in context, the ability to automatically pull and push information to JIRA to plan code changes, and the ability to break your problems down into manageable pieces and sub-divide them among a fleet of sub-agents.
Developers didn't yet have the "Ask -> Plan -> Implement -> Review" workflow that results in the best agent-written code.
Now the tools and developers do and it works incredibly well.
