Michio Kaku’s idea of the cave man principle is a great representation and a great example of the way communication and human interaction with each other has stayed the same. Humans have always wanted proof of the kill it’s one thing to see a picture of something famous but amazing to be able to tell someone you actually got to see it in person and be there looking at it. our ancestors were like this and that’s exactly where we get it from. Our social interactions 100’000 years ago would be like how we interact today but in different ways. The cave man would draw stories on the walls where as we would use our hands and our voices or the t.v. Our social interactions 100,000 years into the future would be the same as they are now and they same as they were 100,00 years ago it would just be more advanced and maybe less face to face as it used to be.
