Data Is Everywhere

Data is a fancy word for recorded facts. Your height, the temperature outside, how many goals your team scored, the song you played three times in a row last week. If someone wrote it down, it is data.

Where data comes from in your life

Your phone tracks steps and sleep
TikTok records every video you linger on
School grades go into a database
Your location pings a cell tower every few minutes
Smart speakers log every time you say Hey Siri

The modern world runs on data. Every app you open, every game you play, every purchase your family makes is adding rows to some company's database. You are generating data right now, just by reading this lesson.

Why AI cares about data

AI models like Claude and ChatGPT are really just very complicated pattern-spotters that have been trained on enormous piles of data. Without data, there is no AI. The whole field depends on humans generating mountains of recorded facts, which machines then study.

In God we trust. All others must bring data.
— W. Edwards Deming

The big idea: data is just recorded facts, and once something is recorded, machines can study it. You are both a consumer of data and a producer of it, every minute of every day.
