What an amazing illusion we humans have created

What an amazing illusion we humans have created. We’ve created the illusion that the computer is filled with text and text has lines. The illusion is so complete, so compelling, that we have an incredibly hard time thinking there could be anything other than text inside our computers. And we’ve build a whole tower of stuff on top of the illusion: text editors, text data formats, text programming languages, social media, and so forth.

But in fact, there is no text in the computer, just numbers. And there are no lines. The numbers inside the computer are interpreted by clever software to represent letters and those letters are displayed on a monitor. Certain numbers are interpreted to represent an end-of-line marker, the succeeding numbers (er, letters) are displayed on the next line of the monitor.

The power of abstraction – amazing!
