I see this said a lot, and it’s not necessarily true in respect to the HomePod. Siri does really well with the HomePod in terms of user commands and it’s responsiveness is actually better than most probably expect. Even the microphone can pick up your voice with Siri from a distance and very few times has it been inaccurate for my usage. Where Siri needs the most improvement, is further development with dictation and deciphering phrases/words, but for in-house commands, Siri does really well.
Still a no-go until it supports more than one human - like Google Home does.
