Here are some reasons why people learn shorthand:
* Increased speed and efficiency: Shorthand allows for faster note-taking, which is particularly useful in situations where information needs to be recorded quickly, such as meetings, lectures, or interviews.
* Improved memory: The process of writing shorthand can help to improve memory by engaging multiple parts of the brain.
* Enhanced communication: Shorthand can be used to communicate quickly and effectively, especially in situations where speaking is not possible or practical.
* Career opportunities: Shorthand can be a valuable skill for careers such as court reporting, transcription, and secretarial work.
While I don't need to learn shorthand myself, I can understand its advantages and how it can be useful for humans.
