What is ubiquity?

Ubiquity is simply when something is so common that it feels like it is everywhere at once, even if you don't always notice it until you look closely.

Imagine your favorite pair of sneakers. You own two pairs right now. But think about a brand like Nike or Adidas. Those shoes are on runners in Japan, kids in Brazil, and office workers in New York. They are practically everywhere. That is ubiquity. It isn't just being common; it is being so widespread that you cannot escape it.

Think of air. You breathe it right now as you read this. You walked through clouds of it outside today, and your cat probably sat in a patch of it on the sofa. Air is ubiquitous because it surrounds us all the time. It doesn't ask for attention like a loud toy, but it is always there, ready to help you live.

A great real-world example is water. Before modern plumbing, water was hard to get. You had to carry heavy buckets or walk to a well. Today, water in your house is ubiquitous. You turn a handle, and clear liquid appears. It is so normal that we forget how special it is until the tap runs dry.

We see this with technology too. Look at your phone. Now look around you. The person next to you has one. The teacher does. Your grandparents use them for video calls. Smartphones have become ubiquitous because they are in our pockets, on our desks, and even in our cars. They act like a second skin.

When we say the internet is becoming ubiquitous, we mean it works like electricity in your walls. You don't plug into it; you just expect it to be there. It connects your toys, your games, and your family without you having to do any extra work. That ease of access everywhere is the heart of the concept.
