I'm just grateful that Duolingo didn't forget about the robot. And how appropriate for it to show up here, in the art section. I know that when I go to the art museum the robot display is one of my first stops. ;-)
Well, something being robotic usually has a negative connotation in art, implying it's lifeless or trite. And with this whole lesson being centered around art, it was the first thing that came to mind.
