If he takes care of himself he could pull a Dick Clark and last forever. The question is what happens if/when Paula or Simon leave?
Today’s kids won’t acept an old guy..a la Dick Clark. But you do raise an interesting question as to Simon and Paula. So, let’s consider it, but in a different light. Assume that Simon and Paula went out on a date together last night, to celebrate the conclusion of the season, and on the way home their car gets wiped out by a drunk driver...(or whatever scenario you choose to imagine ) now, as a producer of AI, you’re faced with having to replace both of them immediately. So, who would you pick, right now?
