As close to machine learning as the cannabis industry has come, Mootia is a smart grinder that automatically determines the speed, direction, and power required to grind based on readings of what's in its chamber, then deposits what it mills into a pre-roll cone. It's not made for storing ground weed. It's made for smoking freshly cut marijuana.
