Kelly is about to fly off to do research a week, so we were out having a nice dinner downtown. We had an interesting conversation in which we reached a cute conclusion. Here’s the logic:
1) Wherever you have self-replicating machines that mutate, you will have life.
2) Since life should arise in small bits, rather than fully formed, life will probably be made of lots of small self-replicating machines, which also experience mutation.
3) Some of those mutations will result in uncontrolled replication
THUS, if we were to meet aliens, the one disease they’d definitely have in common with us would be cancer.
