Defending Computer Science & Engineering in a life raft debate

What is a life raft debate ? In the Life Raft Debate, we imagine that there has been a nuclear war, and the survivors (the audience) are setting sail to rebuild society from the ground up. There is a group of academic-types vying to win the coveted Oar and get on the raft, and only one seat is left. Each professor has to argue that his or her discipline is the one indispensable area of study that the new civilization will need to flourish. At the end of the debating, the audience votes and the lucky winner claims the Oar and climbs aboard, waving goodbye to the others. Maybe a discipline worth its own salt would be able to built their own boat, no? Or a good discipline would have documented their findings so well and made itself a science rather than an art, so a practitioner is not needed to transfer information. Which discipline do I think should be the discipline to go? Let me tell you, I would oppose having a computer science and engineering person on the boat before we make sur
