I'm glad I could contribute! It's been a fun read and a fun journey.
My reasoning behind why "open" wasn't sufficient as it was shown not to be, was quiet obviously because open what? A can of tuna? 😂 When dealing with voice activated commands you need to be super specific to what you're asking it to do. Which is why "open the doors" was a command it executed.
I'm enjoying following an authors journey by collecting data from their readers perspectives and how you're then weaving that into the story. It's very immersive.
