A.Technology can make us more productive but it can also make us less productive. For examples computers and new technology machines make jobs alot easier for example the internet makes it much easier to find information. An example of technology being less productive is when we are in school and always using are cell phones for texting instead of doing are work.

B.Yes multi-tasking is really task switching. It is task switching very quickly and because we are switching tasks very quickly we pay very little attention to one task instead of if we were just doing one thing and giving it our full attention. The consquences of this can be car crashes etc. Very little productivity for a single task.

C.I think that it is not true and that young people do know things in depth. Although knowledge for kids is quite easy to access they still know things in depth in may be different from what the last generation knew in depth though. What kids know in depth today is technology kids know everything about technology alot more then the older generation. Kids know technology in depth where as the older generation know other things in depth etc.
