I've been daily-driving a mac for 10 years now and I've only ever triggered Siri by accident. I do use it pretty regularly on the phone, mostly to set timers, get directions, and call contacts, but I've been well trained over these years to not expect it to be capable of more than that.

I remember it being pretty useful on phone. Now, it can't even "like" a song when I'm driving and I want it to add a song to my Spotify favourites list. It could do a few months ago, now it refuses with "sorry there was a problem with the app".

I've had to resort to asking it to take a screenshot so I can go find the song later. Three quarters of the time it never saves the screenshot though, despite seeing the screen flash out of the corner of my eye.

Your training is now out of date.
