Aren't they supposed to be saying "ninja" now? Though, I guess even that word is getting long in the tooth. I wonder what the next hyperbolic word for "expert"

Aren't they supposed to be saying "ninja" now? Though, I guess even that word is getting long in the tooth. I wonder what the next hyperbolic word for "expert" will be? Personally I've alway felt more like a plumber or carpenter than a rockstar or ninja.
