"You haven't used a PDP-10, how would you be able to deal with a smartphone?"
He didn't talk about old technology like 'smartphones', which existed as products (Nokia Communicator, ...) 20 years ago, but claimed that much better 'futuristic' IDEs for Lisp are possible, though what he claims may currently only exist in his imagination...
You are misinformed. I'm using a GNU Emacs (-> Aquamacs) on the Mac and cut/paste/copy are invoked with the usual command keys. But usually I use the LispWorks editor, which is also in the Emacs family, and even there cut/copy/paste is the usual command sequence... Both editors are built with excellent Lisp support. One is written in C + Emacs Lisp and the other one in Common Lisp.

You haven't even understood the old part, how would you be able to deal with the futuristic part?
