Your standard full-stack dev is going to have "less experience" with approximately 80% of her codebase, by dint of having a finite life-span. ChatGPT is a faster and more convenient SO in that (very common) case. I, for example, have used it with great effect writing bash scripts that I would not dare to write otherwise. It's also not bad at bashing out the first use of a new library. I mean, I have ended up throwing that code out 100% of the time, but it's still useful.
