Metcalfe's law

Metcalfe's Law is like a rule for how something will change in value when it grows bigger. It says that when something gets bigger, its value grows even more. For example, when you have one person, it is not very valuable. But if you have two people, they can talk to each other and it is way more valuable. The same goes for many things - like phones, houses, or even websites. The bigger they get, the more valuable they become!
