Using ChatCPT to help you after you have been stuck and struggled would be equivalent to asking a senior. A senior might hallucinate an answer too, but either way you will get pointed in a generally useful direction. That’s usually all it takes

But as a senior, I can’t imagine using an LLM at this stage for solving anything meaningfully complex.

A friend of mine in a senior role uses it all the time and says it 2-3x'd their productivity. He architects everything using experience but simple but time-consuming sub-routines are done via an LLM. He also uses it to create tests for his code and is quite happy with how it performs in these areas.

What language does he program in? ChatGPT and CoPilot have increased my productivity, sure, but I don't know if they've multiplied it by 2, and definitely not 3. I mostly program in Rust, and while they are good, they still often produce things that don't compile. Iterating back and forth to get something that works takes time, and it feels to me like sometimes doing it alone would've been almost as quick.

I could possibly be way off in my estimations, though. A true comparison would be having me do a task with and without it, but of course once I've done it once, the next time I will do it faster.

They use CoPilot integrated into their IDE and mostly program with Kotlin.
