If they are only used to play music and set timers then users are not really trying. My Google Assistant is frequently used to answer questions that come up in conversation (with people), translate or define a word heard on some show, or look up some fact. All while sitting on an easy chair while eating or otherwise occupied, and not wishing to fumble with a mobile device.
My only complaint is that Google Assistant seems to be hard of hearing, but that should be fixable.
