You have lost any idea and concept of what is a program, what is software.
With your arguments all is text and the Bible tells "in the beginning there was th WORD"
Windows Vista is a text file, any virus is a text file.
The human interface until computers are able to read your mind (if there is something to read) is the keyboard, so any virus maker types A, B,C,... in his keyboard to make a virus.
Binary file doesn't exist, text is the only thing that exist, if you look at Poser.exe you will find
4D 5A 90 00 03 00 00 00 04 00 00 00 FF FF 00 00 B8 00 00 00 00 00
.......
Text file again and a bomb is made of text files too.

The fun goes on....

Stupidity also evolves!
