So who has done the math on the price point where offshore coders are cheaper than LLMs? They both need good specs, guidance, and validation of their work. So it seems to me that when the effort to manage people vs. the effort to orchestrate LLMs is about the same, and the price is about the same... what are we actually gaining here?

I can only imagine the cost of maintaining the 100K+ LOC codebases that are slopped out today. We can't keep growing the context windows and amount of agents, right? Or do we stick with greenfield projects?
