In what speech did Richard Riley, Sec. of Education under Clinton make this statement?
We are currently preparing children for jobs that don’t yet exist…

Using technologies that haven’t yet been invented…

In order to solve problems that we don’t even know are problems yet.

And a lot more of those jobs don't exist today
