Except that voice assistant are not self-discoverable (in addition to being very unreliable and sluggish, which granted could be improved over the long run). And it forces me to memorize commands. Not just "switch on x". But like I want to play that song from that band I don't remember the name of but I remember it is a blue album a few songs after that radiohead song in my playlist. I don't want to have to memorise all these names.
