Indeed, back in my Google Glass days, I could "ok glass" a voice command, but heck if I ever actually wanted to. It's also super awkward in public... and I still look at people strangely today when they "ok google" something or the like.

In a home, I do totally get it. If it wasn't for the always listening microphones, I'd be up for it. But even then... I might ask my house to do something, I'm still going to manually want to type this comment.
