Yes, in a reasonable microservice land where the places you need to connect to are all documented in very concise places, you have have extremely productive $10 days. In the giant monorepo with everything custom, you can't just rely on built in knowledge of 80% of you libraries, so it's a very different world.
A place like Google has to be so much better off just training library concepts in, given how much of the things the LLM will "instinctively" reach for are unlikely to be available. Not unlike the acclimation period what happens when someone comes in or out of a company like that, and suddenly every library and infra tool you were used to are just not available. We need a lot more searching when that happens to us, and the LLM suffers from the same context issue. The human just has all of that trained in after a 6 months, but the LLM doesn't.

They did that, there was a special version of Gemini fine-tuned on internal code. But then the main model moves so fast that it is hard to keep such fine-tunes up to date and on the latest.
