What problems arise if knowledge is communicated only orally?

If knowledge is communicated only orally, it can lead to misunderstandings and misinterpretations, as details may be forgotten or inaccurately conveyed over time. Additionally, the lack of a written record makes it difficult to verify information or refer back to it, which can hinder learning and retention. Furthermore, this method may exclude those who are deaf or hard of hearing, limiting access to information. Overall, oral communication can result in a loss of nuance and context essential for fully grasping complex ideas.
