Monoculture is a terrible idea, even in a robotic vertical farm with sterilization. Decentralization is key, but brexit tyrants like Dyson will never share their automation technology or research with the public. Open source sharing is the only way to bring the price down to the point it can be decentralized.

Also, his vertical farm would not be profitable without his biodigesting power plant that gets free high-quality fuel from his non-vertical farm empire.
