Maybe it's different with Alexa (I use Google Home), but I disagree with the premise of the article. Firstly, for a product that you use every day I don't see it as much effort to learn to say the right commands. Once you know it, you don't unlearn it. I also have the Google Hub, and an app for controlling the lightning (Phillips Hue), but I rarely interact with those, since via that route it takes more steps and more time to get what I want.
