This is a very good question.
Humans can't live without communication.
To be able to learn, you would have to communicate with someone or something. To be able to do basically anything, you would have to communicate with someone. Communication is a big part of our lives and a lot of misunderstandings, and conflicts can happen as well. When we don't communicate properly to each other, we can get the wrong idea. When we don't communicate to people, it also makes us feel like we're alone in the world; which is also a big part of not being able to communicate. Mental health and learning takes a lead on our lives. Without those important things, it can equal to a very lonely future.
To conclude, we need communication.
I hope this helped! :)
