The big idea
Unlike your brain, an AI brain is just a really big file. It can be copied and run on millions of phones or computers at the same time. That's why AI can talk to so many people at once.
Some examples
The same AI helps millions of kids with homework at the same moment.
An AI weather model can run in every weather app on Earth.
Game studios copy one AI character brain into thousands of game enemies.
Voice assistants on every phone use the same copied AI brain.
Try it!
Imagine if you could copy your math homework brain to a friend in seconds. AI already does that!
