Huh, interesting. I periodically ask Siri "hey siri, are you actually smart yet?" (or variants on this depending on how I feel). So far I've always received a polite "I'm sorry, I don't know how to do that". No worries, you'll get there.

It's funny how the unexpected is way more impressive. I tried out the voice commands on my new car (BYD) and after it correctly interpreted and implemented my request, I politely said "thank you!" (as I always do, it's important to set a good example) and the car responded "you're welcome!". 100% could just have been a lucky setup for a scripted response... but...
