All these hot takes that LLMs are -10x, 100x, 2x are kind of silly. It really depends on:

What you are using it for? What language, what framework, how many LOC, what domain, how much docs can the LLM read, etc etc.

What are you optimizing for? Cost? Human knowing how your code works? Getting something out the door?

How Good You Are at Prompting the LLM for THAT specific set of parameters?

I find AI can save me like 5x time on something, and in other cases it's wasted 5x time. Overtime I'm hopefully learning how to use it better.
