Raw LLM Responses

If AI replaces devs, it also replaces tech companies. What exactly is their mote except the cost of development? What happens when I can tell an AGI agent "here's my company's and sales force's user docs. Do everything a Salesforce consultant would do and optimize for my use cases." There wouldn't necessarily even be any code. Eventually, AI wouldn't need to write code in "files" and "use a compiler" like himans need to. It would just be this abstract agent that you tell to do things. It's not clear to me how automating automation isn't just the end of bussiness in general (assuming it doesn't kill us all at that point, which it definitely will. Don't look into it, it's too late.)
