But it isn't designed to be a replacement for a 5.2, 7.1.4 etc system. But a pair of them with an AppleTV could absolutely be your 2.1 system for watching Netflix and listening to Apple Music.
Something as simple as “Hey Siri turn the living room lights off” is often turned into a full discussion because it misheard “turn” and is too stupid to infer it from the rest of the sentence.
The real time translation for the 5 or so supported languages is pretty incredible. I use it when I can’t think of the correct French to use if I have a worker visit my house (like an electrician, etc.)
Google is under appreciated — imo its way more capable.
HomePod Siri is dumber, which 10x the irritation.
I would say Siri has been the worst of the three. Even an Apple centrist website shows how they are falling short.
