I’ll be honest, it’s probably wasted more time than it’s saved me. I only trust it to format files and find where things might be used in the code base. So, you know, plain-language pretty print and grep.

I concur, it has gotten me in multiple wild goose chases when debugging. It is extremely confident especially when it's wrong

It's pretty good at fleshing out documentation. and if you're naming variables properly it's pretty good at gleaning what you're trying to do and autocomplete on a small scale.
