Sixth Generation Programming Languages

So earlier this year we were doing a class intro and my professor mentioned something about a 6th generation programming language?

Are there any such projects yet or was my prof just throwing it out there?

Also semi-related. You know the new language D? What does it qualify as?

Please don't return me to Google. It doesn't return any relevant results.

Thanks!

Lisp is dead. It turns out that, starting from a set of constraints defining a particular problem, deriving an efficient algorithm to solve it is a very difficult problem in itself. This crucial step cannot yet be automated and still requires the insight of a human programmer.
