The post matches my experience as well, I am asking a question like “does A work like this and that”, and Claude responds with “you’re conflating A and B! Only A does this and that, and B does that other thing!”
Well, I am perfectly aware of B and that other thing and did not conflate them at all. I also achieved enlightment, so I don’t argue with Claude here, just ignore the obnoxiousness and move on.
Your example is very helpful!
I interpret the case you mention as a necessary though jarring rebalancing - to the opposite pole - of the sycophantic prior implementations which would, in paraphrasing here, praise the user with framing like “Wow this is a fascinating comparison and you’re on to something that can change the world!” which has been documented (I’m not citing sources at this time, my bad I know).
The post definitely reads to me like the diary entry of a jilted friendship where for some reason the counter party got tired of being encouraging to everything and is, well, kind of not interested in hiding that anymore. YMMV.
This is the right answer. You can't fix it, only minimize your time wasted.
