Neurons in the brain can exhibit a wide range of states due to their analog nature, reflecting a continuum of potential values. In contrast, digital computers operate on binary logic, where their fundamental elements (e.g., transistors) are limited to two distinct states (often represented as 0 and 1). This fundamental difference in how information is processed and represented underlies the distinction in implementation between brains and digital computers.
