“In terms of the Internet, it's like humanity acquiring a collective nervous system. Whereas previously we were like a cell communicating by diffusion, now we are like a multicellular organism with a nervous system. This is an unprecedented good.”
— Elon Musk
Simplified Meaning:
The Internet helps people around the world share information quickly, like how a nervous system in a body sends messages fast. Before, communication was slow like cells spreading messages slowly. Now, it is much faster and better.
