If someone tells you that those cryptoglyphs on your computer screen are meaningful and coming from a distant country, you believe them. Unless, of course, you stick your finger in the wall socket. In the modern technological world, hearing isn't believing. If it were, television would not exist. The Web, TV's strange child, would never have been born.
Software is eye-dependent.
Those globs of code are nothing more than magnetic images stored on a magnetic medium and transmitted with electronic pulses. You can't see software, you can't smell it, feel it, hear it or touch it. Living on the Internet is not living a real life. It's one thing to watch Sammy Sosa stroke a long ball out onto Waveland Avenue. It's another world to take a swing of your own.
