Complicated multi-variable problems were never easy to Google.
Possible, if you were prepared to put some time in, but still not easy.
That you can explain several paragraphs of the details of a problem as a prompt and get a decent answer is a definitive upgrade.

I mean it is a skill, just not an enormously valuable one.
Its a bit like knowing how to use Microsoft Office. Good to have but not the basis for a hire.
