On the process of building Earthes, the terminal unit said "That's a great machine otaku." when Ion made Noelia G2 Tron. I don't prefer the expression because "otaku" sometimes means scornful in today's Japanese society, but my wife replied in the way of role model for otaku. It fundamentally should be like that.
Ion:
It is not bad to be called "otaku" for something I'm seriously fond of.
