Many objects, devices, and systems are designed with a binary structure, such as switches, on/off buttons, light bulbs, zippers, and binary code. The idea of having a choice between two options is deeply ingrained in decision-making processes, as seen through the use of yes/no or rue/false questions.
The number two also plays a crucial role in various cultural and symbolic contexts. It is often associated with unity, harmony, and balance.
