I think an approach that I tried recently is to use it as a friction remover instead of a solution provider. I do the programming but use it to remove pebbles such as that small bit of syntax I forgot, basically to keep up the velocity. However, I don't look at the wholesale code it offers. I think keeping the active thinking cap on results in code I actually understand while avoiding skill atrophy.
i don't mean to pick on your usage of this specifically, but i think it's noteworthy that the colloquial definition of "rubber ducking" seems to have expanded to include "using a software tool to generate advice/confirm hunches". I always understood the term to mean a personal process of talking through a problem out loud in order to methodically, explicitly understand a theoretical plan/process and expose gaps.
based on a lot of articles/studies i've seen (admittedly haven't dug into them too deeply) it seems like the use of chatbots to perform this type of task actually has negative cognitive impacts on some groups of users - the opposite of the personal value i thought rubber-ducking was supposed to provide.
This is what human language does though, isn't it? Evolves over time, in often weird ways; like how many people "could care less" about something they couldn't care less about.
