While "useless knowledge" can be a fun and engaging conversation starter, relying solely on it as a primary means of connecting with strangers may have drawbacks and limitations. One potential drawback is that not everyone may share the same level of enthusiasm for obscure facts or trivia, which could lead to a disconnect or lack of engagement in the conversation. Moreover, focusing too much on trivial information may overshadow the opportunity to delve deeper into meaningful topics or personal experiences that could foster a more genuine connection. To address these limitations, individuals can strike a balance between sharing their unique knowledge and actively listening to others, allowing for a more balanced and reciprocal exchange of ideas. By being mindful of the other person's interests and adapting the conversation to accommodate different preferences, one can create a more inclusive and enriching interaction.
