I don’t think it’s odd, because LLMs are just way faster than any junior (or senior) Dev. So it’s more like working with four junior devs but with the benefit of having tasks done sequentially without the additional overhead of having to give tasks to individual juniors and context switching to review their changes.
(Obviously, there are a whole lot of new pitfalls, but there a real benefits in some circumstances)
I agree this feature enabled by default so people tech literate enough can just turn it off would be great for several people I know, just not from Google.
