Why is it so hard to properly parse the wake word? My Google home turns on all the time from background noise. Is there a specific technical challenge that makes it hard to avoid these false positives?

love how openly biased and full of shit everyone on HN is. Google does it and the world is ending but apple does it and not a peep

Is anyone surprised by this?
