# Digital future
You can look at crypto as coins, technology, etc. Simply put, it's a network.
A network was created for people to do things together — to exchange and make contracts.
Just like the Internet[^1] or mobile communication. Basically, it is something that bonds people together.
Assuming a crypto network is useful for the planet, it will go through a process of growth from its first users to network saturation. And so, [Metcalfe's law](#user-content-fn-2)[^2] can be applied: the value of a network is proportional to the square of the number of connected users of the system.
Crypto is growing almost twice as fast as the internet in the late 90s and early 00s. It is the fastest-growing network the planet has ever seen.
There will be [other networking tech](#user-content-fn-3)[^3] that will also grow, possibly even faster and have the same impact.
Assuming the world needs crypto, the growth trend continues, and then by 2030, more than half of the planet will be using crypto. And it will have the value of the square of users.
[^1]: The Internet as a network will hit a ceiling – the number of people on the planet. For crypto network ceiling will be higher because of the robots connected.
[^2]: FAANG companies — the largest reps of the Internet network — have grown on Metcalfe's network effect.
[^3]: Whats'up AI 👋, the "frontend" of programmable economy.
