The difference is AI is closing on doing the EXACT work with the EXACT info as a junior dev. Give an LLM a Jira ticket and a codebase and it can push a PR. Spreadsheets are great, but that was a tool that minimized effort but didn't remove it. LLMs can directly replace a remote junior with no visible difference already.

Not really though can it, unless that codebase and Jira happens to pattern match correctly somewhere.
I'd say that the difference is just that LLMs have a natural language interface (for good or for ill).
