The slowness is a feature. The “smart” or “ai” or “fuzzy logic” or “buzzword” cookers take longer to cook the rice than a simple cheap cooker or a pot on the stove. The rice comes out better that way.
Induction Coil ones like in the video takes 2-3x longer for nicer rice. Which is pain in the ass for people use to 20m stove top rice. But fine if you make 5 cups and eat over multiple days.
