How to work with the New Machines

As I said on my last post technology are developping new machines and how we will work with it? How old people will work with it?

Sometimes it's harder to teens work with some machines i don't imagine with old people that cannot understand the technology better than teenagers. On the world of the work a lot of new machines are appearing and we must be prepared to work up with that revolutionary technology.

How? Developpers of that kind of technology should offer some classes to work with it and to explain the functions of machines because sometimes people have for example a mobile phone with a camera and radio and the person only knows to use the camera. We must know all the types of functions of that new technology.
