If there is no difference between a program and data, why are the two words used?

a program is a special class of data.

That special class of data can improve a machine or create a new machine.

Why would this special class has this ability and other classes of data don't? The article explains that programs and non program data can't be distinguished in this manner. The technology doesn't work in a manner that permits such a distinction.

The difference between program and data is a matter of context. It is not a matter of relationship with the machine. A program need not be instructions to the CPU and the same data may be program in some context and not be program in another context. But the bits stored in memory are the same. Whether or not they are called program depends on context.

DNA is "just" information. Change a few bits and you get a new organism.
The organism is not DNA. Please don't confuse the symbols and their semantics.

A blueprint is just information, change a few bits and you'll get a completely
different object when you follow them to build something.
