I haven’t noticed much degradation, and I ask it fairly technical questions related to code and physics topics. What I have noticed though is needing to qualify my statements more, to avoid having it go down the wrong chain of conversation and getting stuck in a suboptimal context. By this I mean having to say things like “I have installed <package XYZ> per the documentation and am familiar with the API” or “assume the reader is already familiar with <foundational topic>, do not simply your explanations.” Otherwise I get stuck in a situation where it talks to me like a kindergartener or spends 3-4 additional rounds of querying just getting through the basic boilerplate. Maybe this was always the case, and posts like these are just subconsciously influencing me.

Plugins like AskYourPDF and Wolfram have been a huge boost though. I can feed it whole textbook chapters and have it summarize sections, solve problems, generate new exercises, and generally help with learning in ways previously unavailable.
