Honestly, I can forgive the lack of context awareness. That's a hard problem. I have issues even getting consistent responses to the same query over time (even back to back in some cases). Sometimes, Siri will misunderstand me and fail to do the thing, but then I look at the text that's transcribed...and it's correct (I.e. the backend was replying to a different transcription than I saw on the frontend).

I've just been trained to not bother. Unless I'm setting a timer, I just don't try anymore.
