Although Marshall McLuhan was not able to experience the modern day technologies, his theory that the medium is the message still applies to the current day.
The medium is most definitely the message. The idea that everything we use, is an extension of us, has well and truly been around for many years. For example, it even applied to the caveman, for he used a rock, to kill the cow.
Not only has it been around for years, but the theory will be forever existing. This is because even in todays society, it could not be more true. The simple fact that I’m typing this message to you, proves that indeed the objects we use, are extensions of ourselves, and that in fact ‘THE MEDIUM IS THE MESSAGE’.
