The proposal regarding lab-grown minibrains is to use them as a model system to study brain development and function, as well as neurological disorders. In the context of creating biocomputers, researchers are exploring the use of minibrains as a way to build neural networks that can be integrated with computer chips, potentially leading to new types of computing architectures that are faster and more energy-efficient than conventional computers. However, this is still a very new and experimental field, and there are many challenges to be addressed before practical biocomputers can be developed using minibrains or other types of biological neural networks.
