Her videos show her engaged with various hardware projects-- making them and explaining them. The article concerns the slander that these projects aren't hers; that she is merely a mascot presenting the work of her (male, engineer) boyfriend. To notice "a mind at work" in the videos, is to suggest that the videos are her authentic work.
