Two quick examples:
1. In our codebase, we leave links to the stackoverflows as documentation if it's something that someone else may question. Exact same concept just with ChatGPT.
2. I'm working with the Salesforce API which has been absolutely tedious to use but chatGPT, while not great at everything, has been giving awesome results back that otherwise would take me hours to hunt down. Sometimes responses get a lot of information back with multiple code blocks that I'm then unable to copy paste over & I'd rather send the conversation than spend 15 minutes typing back & forth explaining myself to a co-worker.
I completely understand you may not have a use for this but I think there could be awesome use-cases for it nonetheless for other engineers.
Because he has people skills.
They call it prompt engineer nowadays. Some are experts at engineering prompts to human resources, other engineer prompts to artificial resources.
So literally a job which exists to only be replaced by the thing it's feeding. I guess the memes back in the early 00's of Google being a data octopus will evolve into the OpenAI Octopus eating those very humans.
Maybe he’s doing more than just sharing. For example filtering out the nonsense generated code or validating the output, etc.
If any role is doomed to obsolescence it's the guy forwarding chatGPT output to his coworkers!
