." WE ARTIFICIAL INTELLIGENCEN'T DEAD yet," Frank Fahrenkopf insisted last month on "The Daily Show", a United States television program. Jon Stewart, the bunch, looked sceptical. Mr Fahrenkopf leads the Earnings on Presidential Controversies (CPD), a non-partisan physical body whose exclusive objective is to organise match-ups every 4 years. This year his team will certainly have nothing to do with all of them. In May, after signalling that he might not get involved in all, Joe Biden challenged Donald Trump to discuss him-- on Mr Biden's conditions. Mr Trump conceded. The presidential candidates are going to face off twice. Extraordinarily, news systems, rather than the CPD, are going to host the meets. They will definitely happen months earlier than they usually would. The first is scheduled for June 27th. Exactly how will these new agreements modify presidential disputes?
