There are many tools people use to communicate in 2023.  Email, phone, text message, and direct message on social media platforms are some of the most common; however, people still write letters and send post cards to one another at times as they have for generations.  Another form of communication is in-person communication where groups of people will get together and communicate on a given topic.  This could be at work in a meeting or a group of friends getting together for dinner to catch up.  This form of communication requires no other tools than one's own voice.
